Newtons Three Laws of Motion Flashcard

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed with the formula F=ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is friction?

Back

Friction is the force that opposes motion between two surfaces in contact with each other.

Front

What is inertia?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p=mv (momentum = mass x velocity).

Front

What is an example of Newton's 1st Law of Motion?

Back

When a horse stops suddenly, the rider continues to move forward due to inertia.

Front

What is an example of Newton's 2nd Law of Motion?

Back

A sports car accelerates faster than a tow truck when the same force is applied because it has less mass.

Front

What is an example of Newton's 3rd Law of Motion?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.
