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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is inertia?

Back

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

Front

How does gravity affect objects?

Back

Gravity pulls objects toward each other; the more mass an object has, the stronger its gravitational pull.

What is an example of Newton's 1st Law in everyday life?

Back

A book resting on a table will remain at rest until someone pushes it.

Front

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

Back

A heavier object requires more force to accelerate than a lighter object.

Front

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

Back
