Newtons Laws

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 an unbalanced 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 F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the formula to calculate force?

Back

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

Front

What happens to an object when the net force acting on it is zero?

Back

The object will remain at rest or continue to move at a constant velocity.

Front

What is inertia?

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 2nd Law?

Back

As mass increases, acceleration decreases for a given force.

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 does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in motion, causing an object to accelerate in the direction of the larger force.

Front

What is the acceleration of an object moving at a constant speed?

Back

0 m/s², because there is no change in velocity.
