## FAQs

**How do you find the tangential and normal components of acceleration?** Use the formulas: at = v^2/r an = v^2/r

Where v is velocity, r is radius of curvature.

**What is the formula for tangential and normal components?** Tangential acceleration at = v^2/r Normal acceleration an = v^2/r

**What are the tangential and normal components of acceleration from position vector?** Tangential component is derivative of velocity vector.

Normal component is derivative of unit tangent vector.

**What is the total acceleration of normal and tangential acceleration?** Total acceleration squared = (at)^2 + (an)^2

By Pythagorean theorem since perpendicular.

**How do you find the tangential and normal vector?** Tangent vector: dr/ds Normal vector: dt/ds

Where r is position, t is tangent.

**Is tangential acceleration the same as total acceleration?** No, tangential acceleration is only the component of total acceleration in the tangent direction. Total acceleration includes normal component too.

**What is the formula for normal acceleration?**

Normal acceleration an = v^2/r

Centripetal acceleration.

**What is the normal and tangential equation of motion?** at = dv/dt

an = v^2/R

**What is the formula for tangent and normal gradient?** Tangent gradient = dy/dx

Normal gradient = -1/dy/dx

**Is tangential component of acceleration always zero?** No, tangential acceleration is only zero when velocity is constant or object moves in a circle.

**Is the tangential component of acceleration zero?** Tangential acceleration is zero for circular motion at constant speed. Otherwise it is nonzero if speed changes.

**Is tangential acceleration always perpendicular to normal acceleration?** Yes, tangential and normal components of acceleration are always perpendicular by definition.

**What is the relationship between tangent vector and normal vector?** The tangent and normal vectors are always perpendicular to each other.

**Is normal velocity always zero?** Yes, normal velocity is always zero since velocity is always tangent to path.

**What is tangential acceleration in simple terms?**

Tangential acceleration causes a change in speed along the direction of motion.

**Does constant speed mean no tangential acceleration?** Yes, if speed is constant, the tangential acceleration is zero.

**What is tangential acceleration directly proportional to?** Tangential acceleration is directly proportional to the rate of change of velocity v.

at ∝ dv/dt

**What are the 3 formulas for acceleration?**

- a = Δv/Δt
- a = 2Δs/Δt^2
- F = ma

**What is the formula for acceleration GCSE?** acceleration = change in velocity / time taken a = Δv/t

**What is the normal unit for acceleration?** The SI unit for acceleration is meters per second squared (m/s2).

**Is Tangential the same as normal?** No, tangential and normal directions are perpendicular to each other.

**How are tangential and normal different?** Tangential is parallel to motion, normal is perpendicular. Tangential causes speed changes, normal causes direction changes.

**How do you find the tangential equation?** Tangential component of acceleration: at = dv/dt

**Is the gradient tangent or normal?** The gradient of a curve is tangent to the curve, not normal.

**What is the slope of normal and tangent?** Slope of tangent = dy/dx Slope of normal = -1/dy/dx

**What is the difference between tangential and normal acceleration?** Tangential acceleration changes speed. Normal acceleration changes direction. They are perpendicular components.

**How do you know if there is tangential acceleration?** If speed is changing over time, there is nonzero tangential acceleration.

**Why is tangential acceleration zero at the bottom?** At bottom of vertical circle, velocity and tangential acceleration are momentarily zero.

**Can tangential component of acceleration be negative?** Yes, if the velocity is decreasing, tangential acceleration can be negative.

**Which always has zero acceleration?**

Normal acceleration is zero for linear motion with constant velocity.

**Why is the normal component of velocity zero?** Velocity is always tangent to the path, so the normal component of velocity is zero.

**Does tangential acceleration change with time?** Yes, tangential acceleration can vary with time if velocity is changing.

**Why does tangential acceleration change with radius?** Tangential acceleration involves v^2/r. For a given v, smaller radius gives larger tangential acceleration.

**Why is tangential acceleration opposite to velocity?** When object slows down, tangential acceleration is negative in direction opposite velocity.

**What is the cross product of normal and tangent?** The cross product of two perpendicular vectors is a third perpendicular vector.

**Is the tangent vector just the derivative?** Yes, the tangent vector is the derivative of the position vector.

**Why is the derivative of the tangent vector the normal vector?** The tangent vector’s derivative is orthogonal to it, which is by definition the normal vector.

**Can a body have zero velocity but no zero average speed?** No, zero velocity means zero speed. Nonzero average speed requires nonzero velocity.

**Can a body have zero average velocity but not average speed?** No, if average velocity is zero, average speed must also be zero.

**Can normal acceleration be 0?** Yes, normal acceleration is zero if motion is linear, not curved.

**What force causes tangential acceleration?** Net force in direction of motion causes tangential acceleration.

**What is the difference between tangential acceleration and velocity?** Velocity is speed in a direction. Tangential acceleration is rate of change of velocity.

**What is the difference between transverse and tangential acceleration?** Transverse acceleration is perpendicular to velocity. Tangential acceleration is parallel to velocity.

**Can an object have constant speed but non zero acceleration?** Yes, if direction changes – e.g. uniform circular motion.

**Can an object have acceleration but constant speed?** No, acceleration means change in velocity, so speed cannot be constant.

**What is an example of tangential acceleration?** A car speeding up or slowing down in a straight line has tangential acceleration.

**Does tangential acceleration change speed or direction?** Tangential acceleration causes a change in speed, not direction.

**Does tangential acceleration change velocity?** Yes, tangential acceleration is the rate of change of velocity vector.

**Is tangential acceleration slowing down?** If speed is decreasing, tangential acceleration is negative, slowing the object.

**What is the easiest acceleration formula?** a = Δv/t Acceleration is change in velocity over time.

**What are the 4 equations for acceleration?**

- v = u + at
- s = ut + 1/2at^2
- v^2 = u^2 + 2as
- s = (v + u)/2 x t

**What are the big five acceleration equations?** The main 5 kinematic equations involving acceleration are:

v = u + at s = ut + 1/2at^2 v^2 = u^2 + 2as s = (v + u)/2 x t v = (Δs)/t

**How do I solve for acceleration?** Rearrange equation v = u + at to get: a = (v – u) / t

**What is the formula for acceleration step by step?**

- Identify initial & final velocities (u & v)
- Identify change in time (t)
- Acceleration (a) = change in velocity (v – u) divided by time (t)

**How do you write acceleration in an equation?** Acceleration in an equation is usually written as a lowercase a, or sometimes α.

Examples: v = u + at F = ma

**What is the unit of acceleration GCSE physics?** The unit of acceleration in GCSE physics is meters per second squared, or m/s2.

**What is the unit for acceleration GCSE?** Meters per second squared (m/s2) is the unit of acceleration in GCSE physics.

**Why are there 2 units for acceleration?** m/s2 and m/s/s both refer to meters per second per second, the unit of acceleration. They are interchangeable.
