Forces and Motion Review

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, dependent on the object's mass and the gravitational field strength.

Front

How does weight change with location?

Back

An object's weight can change based on its location due to variations in gravitational force, such as being on Earth versus the Moon.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases, assuming constant gravitational force.

Front

What happens to two identical cars colliding head-on at equal speeds?

Back

Both cars will stop due to the conservation of momentum.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, which depends on their masses and the distance between them.

Front

Which has the greatest gravitational force: a marble and a baseball, a freighter and Earth, the moon and an astronaut, or the moon and Earth?

Back

The greatest gravitational force occurs between the moon and Earth.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the reaction force when you place a cup on a table?

Back

The reaction force is the force of the table on the cup.

Front

What is an action force?

Back

An action force is the initial force exerted by one object on another, such as a tennis ball hitting a racket.

Front

What is inertia?

Back

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