Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

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

Front

What is Newton's 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 (F = ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the standard unit of force?

Back

Newtons (N).

Front

How do you calculate force?

Back

Force is calculated using the formula: Force = mass x acceleration (F = ma).

Front

What does inertia refer to in Newton's First Law?

Back

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

Front

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

Back

Heavier objects require more force to accelerate than lighter objects.

Front

If a 40 kg student is pushed with a force of 30 N, what is the student's acceleration?

Back

0.75 m/s².

Front

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

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration = net force / mass (a = F/m).
