Newton's laws

Question 1

Define Newton’s 1st Law

Answer 1

A body will remain stationary (or zero velocity) unless an external force is applied.

Question 2

Define Newton’s 2nd Law

Answer 2

When a force acts on an object, the change of momentum
experienced by the object is proportional to the size of the force and the direction in which the force acts.

Question 3

Define Newton’s 3rd Law

Answer 3

For every action there is an equal and opposite reaction.

Question 4

Give a practical example from football or chosen to explain Newton’s 1st law

Answer 4

The ball (body) will remain stationary on the penalty spot until it is kicked (external force).

Question 5

Give a practical example from football or chosen to explain Newton’s 2nd law

Answer 5

When a goalkeeper takes a goal kick, the more force he applies
to the ball with his foot, the faster it will accelerate and the further it will travel.

Question 6

Give a practical example from football or chosen to explain Newton’s 3rd law

Answer 6

When heading the ball, the more force that the player applies to
the ball, the more reaction force will be applied back in the opposite direction from the
ball to the head.
