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 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. (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 is the formula for calculating force?

Back

F = M x A (Force equals mass times acceleration).

Front

If a 10 kg object is accelerating at 5 m/s², what is the force acting on it?

Back

F = M x A = 10 kg x 5 m/s² = 50 Newtons.

Front

What does it mean for forces to be balanced?

Back

Balanced forces mean that the total net force acting on an object is zero, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a net force that causes an object to accelerate or change its motion.

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 if the force remains constant.

Front

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

Back

A soccer ball remains at rest until kicked (an external force acts on it).
