Energy and Newton's First Law of Motion

Front

What happens to gravitational force as the distance between two objects increases?

Back

It decreases.

Front

Objects with greater _________ also have greater inertia.

Back

mass

Front

Which of the following never changes no matter where in the universe?

Back

mass

Front

How does the absence of friction affect a marble traveling on a long, straight path?

Back

The marble would remain at a constant speed.

Front

Which model has greater gravitational attraction?

Back

Model A

Front

Define inertia.

Back

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

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, which depends on its mass and the gravitational acceleration.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.
