4-2 Centripetal Force and Acceleration

Front

What keeps the water in a bucket when swung in a circle?

Back

Inertia

Front

Centripetal force is defined as:

Back

the inward force acting on a body moving at constant speed in a circle.

Front

What is the unit for centripetal force?

Back

N (Newtons)

Front

If car A and car B are both traveling at the same speed, which will require a higher centripetal force?

Back

Car B.

Front

What represents the acceleration of a ball in circular motion?

Back

A (referring to a specific diagram or graph).

Front

Define centripetal acceleration.

Back

The acceleration directed towards the center of a circular path, calculated as a = v²/r.

Front

What is the formula for centripetal force?

Back

F_c = m * a_c, where F_c is centripetal force, m is mass, and a_c is centripetal acceleration.

Front

What role does gravity play in circular motion?

Back

Gravity can provide the necessary centripetal force in certain scenarios, such as a satellite orbiting Earth.

Front

What happens to centripetal force if the speed of an object in circular motion increases?

Back

Centripetal force increases as the square of the speed increases.

Front

What is the relationship between radius and centripetal force?

Back

Centripetal force is inversely proportional to the radius of the circular path.
