Newton's Laws

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

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. It can be expressed with the formula F = ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

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 gravity?

Back

Gravity is the force of attraction between all masses in the universe.

Front

What is net force?

Back

Net force is the combination of all the forces acting on an object.

Front

What is friction?

Back

Friction is the force that opposes motion between two surfaces in contact.

Front

What is an action force?

Back

An action force is the initial force applied to an object that causes it to move.

Front

What is a reaction force?

Back

A reaction force is the force that occurs in response to an action force, equal in size and opposite in direction.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv (momentum = mass x velocity).
