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.**How do you find speed with radius?**Speed (v) can be calculated using the formula: v = (2 * π * r * RPM) / 60, where r is the radius of the rotating object.**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.
