Newton's Laws

Front

What is the unit to MEASURE force?

Back

Newton

Front

What does Newton's Third Law state?

Back

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

Front

What is the net force when two equal forces of 400 N are acting in opposite directions?

Back

0 N (They cancel each other out).

Front

If two teams are pulling with the same amount of force, what will happen?

Back

They will not move at all.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What is inertia?

Back

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

Front

What is the first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the second 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.

Front

What is an example of action and reaction?

Back

When you jump off a small boat, the boat moves backward.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = Mass x Gravity).
