Centripetal Acceleration Concept
Vin Diesel is driving his Ford Mustang in a circle at a constant speed. Dr. Doofensmertz says that Vin Diesel is accelerating. Is Dr. Doofensmertz statement true or false?
What is True
What is the centripetal acceleration of a ferry boat that makes a turn with a velocity of 10 m/s and a radius of 30 m?
What is 3.33 m/s2
What happens to an object when the centripetal force is removed?
What is travels in a straight line path off from the circle in a tangent line
How much force does it take to swing a 10 kg bucket in a circle with a centripetal acceleration of 2 m/s2?
What is 20 N
This is the number of seconds per revolution
What is the period, T?

What is 19.6 m
In what direction does centripetal force have to be applied to get an object to move in a circle?
What is towards the center of the circle
A person weighing at 64.86 kg is spun in a circle with an acceleration of 10.3 m/s2. What is size of force keeping him in the circle?
What is 668.1 N
This is the reciprocal of the period and has units "revolutions per second"
What is the frequency?
As an object travels in a circle, which direction is the acceleration always pointing?
What is towards the center of the circle

What is mass and centripetal acceleration
or
What is velocity and radius
or ...

What is 1.85 m/s2
This is the circumference of a circle
What is 2\pi r
How can you increase the centripetal acceleration you feel when you go around a turn in a car? (need 2 answers)
What is increase the velocity or decrease the radius of the turn
A hamster trips in its wheel that has a radius of 0.15 m. What is the velocity of the hamster if it accelerates at 41.7 m/s2?
What is 2.5 m/s
If I decrease the velocity of an object traveling in a circle, does it take more or less centripetal force to keep in moving in that circle?
What is less

What is 15 m/s
When a car is driving around a bend, where does the centripetal force keeping it in a circle come from?
What is friction between the tires and the road
