Newtons 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 a net external 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. This is often expressed as the formula F = m x a.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does the term 'net force' mean?

Back

The net force is the vector sum of all the forces acting on an object.

Front

What is inertia?

Back

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

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is the formula to calculate force?

Back

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

Front

What is an example of Newton's 1st Law in everyday life?

Back

A book resting on a table will remain at rest until someone pushes it.

Front

How does a rocket launch illustrate Newton's 3rd Law?

Back

As the rocket expels gas downwards, it experiences an equal and opposite force that propels it upwards.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration; increasing mass requires more force to achieve the same acceleration.
