Newton's Laws

Front

What is Newton's 1st Law?

Back

An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law?

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?

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

Give an example of balanced forces.

Back

A book resting on a table.

Front

What happens when unbalanced forces act on an object?

Back

The object will accelerate in the direction of the net force.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

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

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What does the term 'net force' mean?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, acting as an unbalanced force.
