Circular Motion Review

Front

What happens to the centripetal acceleration of an object as the radius of its circular path decreases?

Back

The centripetal acceleration increases.

Front

In circular motion, what is the direction of the centripetal force relative to the velocity of the object?

Back

The centripetal force is directed towards the center of the circular path, while the velocity is tangent to the path.

Front

How do you calculate centripetal acceleration (Ac)?

Back

Ac = v^2 / r, where v is the tangential speed and r is the radius of the circular path.

Front

What is the relationship between tangential speed and centripetal acceleration?

Back

Centripetal acceleration increases with the square of the tangential speed.

Front

What is the definition of 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 formula for centripetal force (Fc)?

Back

Fc = m * Ac, where m is the mass of the object and Ac is the centripetal acceleration.

Front

What is the effect of mass on centripetal force?

Back

Centripetal force increases with the mass of the object if the centripetal acceleration remains constant.

Front

What is the difference between rotation and revolution?

Back

Rotation is the spinning of an object around its own axis, while revolution is the movement of an object around another object.

Front

What is the significance of the radius in circular motion?

Back

The radius determines the curvature of the path and affects both the centripetal acceleration and the centripetal force.

Front

How does the speed of stars in a galaxy relate to their distance from the center?

Back

Stars that are further from the center of the galaxy move faster than those closer to the center.
