Rotational Motion Conceptual

Front

What is the direction of the velocity vector in rotational motion?

Back

The velocity vector is tangent to the circle.

Front

In the context of centripetal acceleration, what direction does the acceleration vector point?

Back

The acceleration vector points toward the center of the circle.

Front

How does the direction of acceleration relate to the net force applied in rotational motion?

Back

The acceleration is in the same direction as the net force applied.

Front

What is the direction of the acceleration vector in circular motion?

Back

The acceleration vector is toward the center of the circle.

Front

What is the direction of the force vector in circular motion?

Back

The force vector is toward the center of the circle.

Front

Define centripetal acceleration.

Back

Centripetal acceleration is the acceleration directed toward the center of a circular path, necessary for an object to maintain circular motion.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) = v^2 / r, where v is the linear velocity and r is the radius of the circular path.

Front

What role does net force play in circular motion?

Back

Net force is required to keep an object moving in a circular path and is directed toward the center of the circle.

Front

What is the relationship between speed and radius in uniform circular motion?

Back

In uniform circular motion, the speed of the object is constant, but the direction of the velocity changes continuously.

Front

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

Back

If the speed of the object increases, the centripetal acceleration increases as it is proportional to the square of the speed.
