Newtons Laws

Question 1

What is Newton’s first law?

Answer 1

The law of inertia

Question 2

What is Newton’s second law?

Answer 2

The law of acceleration

Question 3

What is Newton’s third law?

Answer 3

The law of action and reaction

Question 4

What is the law of inertia?

Answer 4

Inertia is the resistance an object has to a change in its state of motion, so in order to overcome an objects inertia, a force must be applied

Question 5

What is an example of the law of inertia?

Answer 5

A football will remain on the penalty spot until kicked

Question 6

What is the law of acceleration?

Answer 6

The acceleration of an object is directly proportional to the force acting on it

Question 7

What is an example of the law of acceleration?

Answer 7

When a footballer kicks the ball on the penalty spot, the acceleration of the ball is equal to the size of the force - the harder the ball is kicked, the faster it will go in the direction the force has been applied

Question 8

What is the law of action and reaction?

Answer 8

For every action there is an equal and opposite reaction

Question 9

What is the relation between the size of the force on the first object and the size of the force on the second object in the law of action and reaction?

Answer 9

The size of the force on the first object is equal to the size of the force on the second object

Question 10

What is an example of the law of action and reaction?

Answer 10

At a sprint start, Usain Bolt pushes back on the blocks as hard as possible (this is the action). As a result, the blocks push forward on Usain (this push forward is the reaction force) and provides acceleration forward
