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 unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is dependent upon the net force acting on it and the object's 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 does the term 'inertia' mean?

Back

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

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 happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

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

Back

Mass and acceleration are inversely related; as mass increases, acceleration decreases if the force is constant.

Front

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

Back

A passenger lurches forward in a car when it suddenly stops.

Front

What is the effect of an unbalanced force on an object?

Back

An unbalanced force causes an object to accelerate in the direction of the net force.

Front

What is the significance of the term 'net force'?

Back

Net force is the total force acting on an object after all the forces are combined.
