Circular Motion Concepts

Front

What is circular motion?

Back

Circular motion is the motion of an object that travels along a circular path. It can be uniform (constant speed) or non-uniform (changing speed).

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 centripetal acceleration?

Back

Centripetal acceleration (a_c) = v²/r, where v is the linear velocity and r is the radius of the circular path.

Front

How does the gravitational force between two objects change with distance?

Back

The gravitational force decreases with the square of the distance between the two objects, as described by Newton's law of universal gravitation.

Front

What happens to gravitational force if the distance between two objects is halved?

Back

If the distance is halved, the gravitational force increases by a factor of four.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the masses of the two objects.

Front

What is the formula for gravitational force?

Back

Gravitational force (F) = G * (m1 * m2) / r², where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

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 direction of the velocity vector in circular motion?

Back

The velocity vector in circular motion is always tangent to the circular path.

Front

What is the effect of doubling one mass on gravitational force?

Back

Doubling one mass will double the gravitational force between the two objects.
