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 with the same speed and in the same direction unless acted upon by a net external force.

Front

What is the Law of Inertia?

Back

It is another name for Newton's First Law, which states that objects will not change their state of motion unless a force is applied.

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 the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is net force?

Back

The combination of all the forces acting on an object, which determines the object's acceleration.

Front

How do you calculate net force when two forces are acting in the same direction?

Back

Add the magnitudes of the two forces together.

Front

How do you calculate net force when two forces are acting in opposite directions?

Back

Subtract the smaller force from the larger force.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

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

Back

A skateboarder continues to move forward when they hit a rock because their body wants to maintain its state of motion.
