Practice: Newton's Laws & Gravity 2024

Front

What changes as the pull of gravity changes?

Back

Weight changes as the pull of gravity changes.

Front

Which law explains why more force is needed to accelerate a heavier object at the same rate as a lighter object?

Back

Newton's 2nd Law explains this.

Front

Why would Barb the llama weigh more on Jupiter than on Earth?

Back

Because Jupiter has more mass, so it has stronger gravity.

Front

What does Newton's Third Law state about actions and reactions?

Back

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

Front

How is Newton's First Law of Motion described?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted on by an unbalanced force.

Front

What is the formula for Newton's Second Law?

Back

F = ma (Force equals mass times acceleration).

Front

What is gravity?

Back

Gravity is the force that attracts two bodies toward each other.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What happens to weight on different planets?

Back

Weight changes depending on the planet's gravity.

Front

What is an example of Newton's Third Law in everyday life?

Back

When you jump off a small boat, the boat moves backward as you move forward.
