Circular Motion

Front

What is the direction of the velocity of an object in uniform circular motion at any point in its path?

Back

The direction of the velocity is tangent to the circular path at that point.

Front

What is the net force acting on an object at the top of a vertical circular path?

Back

The net force is directed towards the center of the circular path.

Front

What is the definition of acceleration in the context of circular motion?

Back

Acceleration in circular motion is the rate of change of velocity, which is directed towards the center of the circle.

Front

What is the term for the act of turning or circling around a point or axis?

Back

Rotation.

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed along a circular path.

Front

What is the relationship between net force and acceleration in circular motion?

Back

The net force is directly proportional to the acceleration of the object, both directed towards the center of the circular path.

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 the speed of an object in circular motion affect the centripetal force required to maintain that motion?

Back

As the speed of the object increases, the centripetal force required to maintain circular motion also increases.

Front

What happens to the acceleration of an object in circular motion if the radius of the circle is doubled while maintaining the same speed?

Back

The acceleration decreases by half, as it is inversely proportional to the radius.

Front

What is the formula for calculating centripetal acceleration?

Back

Centripetal acceleration (a_c) is calculated using the formula a_c = v^2 / r, where v is the speed and r is the radius of the circular path.
