- What is the relationship between diameter and RPM? There is an inverse relationship between diameter and RPM for a constant speed. If the diameter increases, RPM decreases to maintain the same speed.
- How do you convert RPM to radius? RPM cannot be directly converted to radius as they are different units. RPM is a measure of rotational speed, while radius is a measure of length.
- What is the formula for surface speed of a wheel? Surface speed (v) of a wheel can be calculated using: v = RPM * π * d, where d is the diameter of the wheel.
- How do you calculate speed and velocity? Speed is the magnitude of velocity. Velocity includes both speed and direction. Mathematically, velocity (v) is calculated using: v = d / t, where d is displacement and t is time.

- What is the formula for velocity with radius? The formula for velocity (v) using radius (r) is: v = (2 * π * r * RPM) / 60.
- What is the formula for velocity using radius? The formula for velocity (v) using radius (r) is the same as the one mentioned in the previous answer.
- What is circumferential speed? Circumferential speed is the speed of an object at the edge or circumference of a rotating circle. It’s the linear distance covered per unit of time.
- How fast is 3000 RPM in mph? To convert RPM to mph, you would need to know the diameter or circumference of the rotating object. You can use the formula mentioned in question 8.
- How many mph is 70 RPM? This question can’t be answered without knowing the diameter or circumference of the rotating object.
- How many RPM is 50 mph? This question can’t be answered without knowing the diameter or circumference of the rotating object.
- How do you match RPM with road speed? RPM and road speed are matched through the vehicle’s gearing and tire size. Different gear ratios and tire sizes will result in different RPM values for a given road speed.
- How fast is 7000 RPM? The speed corresponding to 7000 RPM depends on the diameter or circumference of the rotating object. You can calculate it using the appropriate formula.
- Is RPM directly proportional to flow rate? RPM is not directly proportional to flow rate. RPM refers to the rotational speed, while flow rate typically refers to the volume of fluid passing through a system per unit of time.
- Does wheel size determine speed? Wheel size (diameter) can influence speed indirectly. Larger wheels can cover more ground in one revolution, potentially leading to higher speeds at the same RPM compared to smaller wheels.
- How does wheel size affect RPM? Larger wheel sizes generally result in lower RPM for the same speed. This is because the circumference is larger, so the same speed can be achieved with fewer rotations.
- How fast is 1000 RPM in mph? To convert 1000 RPM to mph, you would need to know the diameter or circumference of the rotating object. Use the formula mentioned in question 8.
- How do you calculate the speed of a driven gear? The speed of a driven gear is determined by the size of the driving gear, the gear ratio, and the rotation speed (RPM) of the driving gear.
- What is the formula for speed ratio in gears? The speed ratio in gears is determined by the ratio of the number of teeth on the driven gear to the number of teeth on the driving gear.
- How do you calculate the speed of a gear rotation? The speed of a gear rotation depends on the number of teeth on the gear, the gear ratio, and the rotational speed (RPM) of the gear it’s meshing with.
- How do you calculate speed with bigger tires? Speed with bigger tires can be calculated using the formula: Speed = (RPM * New Tire Diameter) / (Old Tire Diameter).
- How do you find linear speed with radius and RPM? Linear speed (v) can be calculated using the formula: v = (2 * π * r * RPM) / 60, where r is the radius.
- Is RPM dependent on radius? Yes, RPM can be dependent on radius. The linear speed of a rotating object (which affects RPM) is influenced by the radius. Larger radii can lead to higher linear speeds at the same RPM.
- How to explain the relationship between diameter and circumference? Diameter is the measure of the distance across a circle through its center. Circumference is the distance around the outer edge of the circle. They are related through the formula: Circumference = π * Diameter.
- What is the formula for angular speed with radius and RPM? Angular speed (ω) can be calculated using the formula: ω = RPM * (2 * π / 60), where RPM is the rotational speed in revolutions per minute.
- How do you calculate distance with RPM? Distance traveled (d) can be calculated using the formula: d = (RPM * Circumference) / 60, where Circumference is the distance traveled in one revolution.
- What is the RPM of a circle? RPM (Revolutions Per Minute) refers to how many complete rotations a circle makes in one minute. For example, if a circle completes 3 rotations in one minute, its RPM is 3.
- What are the 3 formulas for velocity? Three formulas for velocity are:
- v = d / t (distance divided by time)
- v = Δx / Δt (change in displacement divided by change in time)
- v = dx/dt (instantaneous velocity as the derivative of displacement with respect to time)
- What is the formula for acceleration of speed? The formula for acceleration (a) is: a = (Δv) / t, where Δv is the change in velocity and t is the time taken for the change.
- Is velocity same as speed? No, velocity and speed are not the same. Speed refers to the magnitude of motion, while velocity includes both the magnitude and direction of motion.
- What is the relationship between speed and radius? The relationship between speed and radius is that larger radii generally result in higher speeds at the same RPM, while smaller radii result in lower speeds.
- Does speed change with radius? Yes, speed can change with radius. An increase in radius, while maintaining the same RPM, will lead to an increase in speed, and vice versa.
- How do you find velocity with speed and radius? Velocity can be the same as speed if the motion is along a straight line. If you’re referring to circular motion, velocity includes both speed and direction and can be calculated using angular velocity (ω) and radius (r): v = ω * r.
