Back

Law of Inertia.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

Newtons.

Front

What is friction?

Back

A force that opposes the motion of an object, slowing it down.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Forces that are not equal and opposite, causing a change in motion.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
