Centripetal Force Flashcard

Front

What is centripetal force?

Back

The net force exerted toward the center of a curved path.

Front

True or False: An object moving at a constant speed in a circular motion is not accelerating.

Back

False

Front

Calculate the centripetal force required for a 5 kg ball moving at 4 m/s in a circle with a radius of 2 m.

Back

40 N

Front

What is the formula for centripetal force?

Back

F_c = (m * v^2) / r, where F_c is centripetal force, m is mass, v is velocity, and r is radius.

Front

Calculate the centripetal force for a .12 kg ball moving at 3 m/s with a radius of .65 m.

Back

1.66 N

Front

If three rocks with a combined mass of 0.75 kg are spun at a speed of 20 m/s with a radius of 0.5 m, how much centripetal force is required?

Back

600 N

Front

What happens to centripetal force if the speed of the object increases?

Back

Centripetal force increases with the square of the speed.

Front

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

Back

Centripetal force decreases as the radius increases.

Front

What is the relationship between mass and centripetal force?

Back

Centripetal force is directly proportional to the mass of the object.

Front

What is the unit of measurement for centripetal force?

Back

Newton (N)
