Uniform circular motion

Front

What is centripetal force?

Back

Centripetal force is the net force directed towards the center of a circular path that keeps an object moving in that path.

Front

What direction does centripetal acceleration point in uniform circular motion?

Back

Centripetal acceleration points towards the center of the circular path.

Front

How does the radius of a circular path affect the speed of an object in uniform circular motion?

Back

As the radius decreases, the speed of the object decreases.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) = v²/r, where v is the speed and r is the radius.

Front

If an object has a radius of 1.65 m and an acceleration of 3.5 m/s², what is its velocity?

Back

The velocity is 2.4 m/s.

Front

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

Back

For a constant centripetal acceleration, as the radius decreases, the speed must also decrease.

Front

What does the term 'uniform' in uniform circular motion imply?

Back

'Uniform' means that the speed of the object is constant, although its direction is continuously changing.

Front

What is the role of centripetal force in circular motion?

Back

Centripetal force is necessary to keep an object moving in a circular path, preventing it from moving off in a straight line.

Front

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

Back

If the speed increases, the centripetal force must also increase to maintain circular motion.

Front

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

Back

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