Newton's Laws

Front

What is Newton's 1st Law?

Back

An object at rest will stay at rest, an object in motion will stay in motion, unless an unbalanced force acts upon it.

Front

What is Newton's 2nd Law?

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?

Back

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

Front

What is inertia?

Back

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

Front

What is net force?

Back

The combination of all the forces acting on an object.

Front

What is an example of balanced forces?

Back

A book resting on a table.

Front

What is an example of unbalanced forces?

Back

A pencil being knocked off a desk.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the net force remains constant.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F=ma).

Front

What is the effect of gravity on objects in motion?

Back

Gravity pulls objects towards the Earth, affecting their motion and speed.
