CENTRIPETAL FORCE

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

What is the formula for calculating centripetal force?

Back

Centripetal force (F) can be calculated using the formula: F = (mv^2)/r, where m is mass, v is velocity, and r is the radius of the circular path.

Front

What unit is used to measure centripetal force?

Back

The unit for centripetal force is Newton (N).

Front

How does decreasing the radius of a turn affect speed?

Back

Decreasing the radius allows you to keep a higher speed while turning, as it increases the required centripetal force.

Front

What happens to an object in motion when no centripetal force acts on it?

Back

If no centripetal force acts on an object in motion, it will move in a straight line due to inertia.

Front

What role does friction play in centripetal force?

Back

Friction provides the necessary centripetal force to keep an object moving in a circular path, especially in vehicles making turns.

Front

Why is it important to reduce speed on icy roads when turning?

Back

It is important to reduce speed because ice decreases friction, making it harder to generate the necessary centripetal force to turn safely.

Front

What is the relationship between mass and centripetal force?

Back

Centripetal force is directly proportional to the mass of the object; as mass increases, the required centripetal force also increases.

Front

What is the effect of increasing velocity on centripetal force?

Back

Centripetal force increases with the square of the velocity; if velocity doubles, the centripetal force increases by a factor of four.

Front

In a circular motion, what direction does the centripetal force act?

Back

Centripetal force always acts towards the center of the circular path.
