Circular and Gravitation Test

Front

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

Back

The gravitational force decreases by a factor of four.

Front

In which situation would an object NOT be accelerated?

Back

All of these would have accelerated motion.

Front

Where is the axis located in an object that is revolving?

Back

The axis is located outside the object (external).

Front

If the radius of Earth decreased, with no change in mass, what would happen to your weight?

Back

Your weight would increase.

Front

What causes passengers in a car to feel a force pulling them away from a turn when turning a corner at high speed?

Back

The cause of this feeling is inertia.

Front

Define gravitational force.

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of 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

Explain the concept of inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

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

How does mass affect gravitational force?

Back

Gravitational force increases with greater mass; more massive objects exert a stronger gravitational pull.
