UCM Flashcard 1 (F)

Front

What is the direction of acceleration in uniform circular motion?

Back

The direction of acceleration is always towards the center of the circular path.

Front

What happens to an object moving with constant speed and constant acceleration that is perpendicular to its velocity?

Back

It is moving in a circle.

Front

What is the direction of the net force acting on an object in uniform circular motion?

Back

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

Front

What does the term 'uniform' mean in the context of motion?

Back

It means same, constant, or alike.

Front

What is the direction of the velocity of a car going around a curve at constant speed?

Back

The velocity is directed toward the front of the car.

Front

What is uniform circular motion?

Back

Motion of an object traveling in a circular path at a constant speed.

Front

What is centripetal acceleration?

Back

Acceleration that occurs in uniform circular motion, directed towards the center of the circle.

Front

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

Back

The speed is constant, but the direction of the velocity vector is continuously changing.

Front

What is the formula for centripetal force?

Back

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

Front

What is the effect of increasing the radius on the centripetal force required for circular motion?

Back

Increasing the radius decreases the centripetal force required for the same speed.
