Newton's Laws of Motion

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 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

What is inertia?

Back

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

Front

What is friction?

Back

The resistance that occurs when one surface moves over another.

Front

How do you calculate force?

Back

Force is calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What happens to an object's motion when a net force is applied?

Back

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

Front

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

Back

An object with a larger mass requires a greater force to achieve the same acceleration as an object with a smaller mass.

Front

What is an example of Newton's 3rd Law in everyday life?

Back

When you jump off a small boat, you push the boat backward as you move forward.
