newtons laws

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest unless a force is applied, and an object in motion will continue in motion at a constant velocity unless acted upon by a net external force.

Front

What does the term 'net force' mean?

Back

The net force is the overall force acting on an object when all the individual forces are combined.

Front

If two forces are acting in opposite directions, how do you calculate the net force?

Back

Subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What is the Law of Inertia?

Back

The Law of Inertia is another name for Newton's First Law, stating that objects will not change their state of motion unless acted upon by a 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

How do you calculate acceleration using Newton's Second Law?

Back

Acceleration can be calculated by dividing the net force by the mass of the object (a = F/m).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What does 'equal and opposite reaction' mean?

Back

It means that for every force exerted by one object, there is a force of equal strength exerted in the opposite direction by another object.

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 keep moving due to inertia.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = Sum of all forces acting on an object.
