AP Physics 1 Centripetal Force

Front

What is centripetal force?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center of the circle.

Front

How does speed affect centripetal force?

Back

Centripetal force increases with the square of the speed. If speed doubles, the required centripetal force increases by a factor of four.

Front

What is the formula for centripetal force?

Back

The formula for centripetal force (F) is F = (mv^2)/r, where m is mass, v is velocity, and r is the radius of the circular path.

Front

What happens to centripetal force if the radius of the circular path increases?

Back

If the radius increases while keeping mass and speed constant, the centripetal force decreases.

Front

What is the relationship between mass and centripetal force?

Back

Centripetal force is directly proportional to the mass of the object; greater mass requires greater centripetal force to maintain circular motion.

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object in opposite directions that are equal in size, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when two forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

How do you calculate the centripetal force required for an object in circular motion?

Back

To calculate centripetal force, use the formula F = (mv^2)/r, substituting the object's mass, velocity, and the radius of the circular path.

Front

What is the effect of frictional force on a car moving in a circular path?

Back

Frictional force provides the necessary centripetal force to keep the car from sliding out of the circular path.

Front

If two objects with different masses are moving in a circle, which experiences greater centripetal force?

Back

The object with greater mass experiences greater centripetal force if both are moving at the same speed and radius.
