Newtons laws

Front

What is Newton's First 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 Second Law of Motion?

Back

Front

What is Newton's Third Law of Motion?

Back

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

Front

Define momentum.

Back

Front

What does the law of conservation of momentum state?

Back

The total momentum of a closed system remains constant if no external forces act on it.

Front

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

Back

When the force is constant, an increase in mass results in a decrease in acceleration.

Front

What is the formula to calculate force?

Back

Front

If a 92 kg skier experiences a force of 118 N, what is their acceleration?

Back

The acceleration is @@a = rac{F}{m} = rac{118 ext{ N}}{92 ext{ kg}} ightarrow 1.3 ext{ m/s}^2@@.

Front

What is inertia?

Back

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

Front

Give an example of Newton's First Law in everyday life.

Back

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