Newtons Laws of Motion

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 unless acted upon by an outside 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. (F=ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces do not change the motion of an object; the object stays at rest or continues moving at a constant speed.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces cause a change in the motion of an object; it can start moving, stop, or change direction.

Front

What happens when a ball hits the ground?

Back

The ball exerts a force on the ground, and the ground exerts an equal and opposite force on the ball, causing it to bounce.

Front

What is inertia?

Back

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

Front

Can you give an example of Newton's 1st Law?

Back

A book resting on a table will stay there until someone picks it up.

Front

Can you give an example of Newton's 2nd Law?

Back

If you push a toy car, it will accelerate faster if you push harder or if the car is lighter.

Front

Can you give an example of Newton's 3rd Law?

Back

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