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 unbalanced force.

Front

What is inertia?

Back

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

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 is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling us down.

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.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal, causing a change in motion.

Front

What happens to a ball when it hits the ground?

Back

The ball exerts a force on the ground, and the ground exerts a force back on the ball, causing it to bounce.

Front

What is an example of an unbalanced force?

Back

A soccer player kicking a ball is an example of an unbalanced force.
