Centripetal Force Lab Review

Before you can find the centripetal force, you must find the ______.

• Velocity

• Normal force

• co-efficient of friction

• friction force

How is the Centripetal force represented?

• Fc

• Ff

• Fa

• Fn

What is the correct formula to calculate the velocity of an object going in a circle?

• change in velocity / time

• m v squared/r

• 2 pi r/T

• d/t

in the lab, which object represented the radius of the circular path?

• Fc

• number of rotations

• mass of the ball

• length of the string

why did you divide the time for 10 rotations by 10?

• the T is the time it takes for 1 rotation

• the T is for the time it takes for 10 rotations

• T is the time it takes for 100 rotations

• T is the time it takes for 1000 rotations

the car travel around the track one time in 3.5 seconds. the radius of the track is 30 m. What is the velocity of the car?

• .73 N

• .73 m/s

• 53.83 N

• 53.83 m/s

The velocity of a car going around the track is 10 m/s. The track's radius is 5 m. the mass of the car is 89 kg. What is the centripetal force on the car?

• 1,780 m/s

• 1,780 N
