1.3 Newton’s Laws Of Motion

Question 1

Newton’s Third Law states that

Answer 1

For every action there is an equal and opposite reaction.

Question 2

Acceleration is calculated by…

Answer 2

Dividing change in velocity by time.

Question 3

The law of acceleration states that

Answer 3

The acceleration of an object is proportional to the total force applied to it, and inversely proportional to the mass of an object.

Question 4

Force is calculated by the following formula…

Answer 4

Mass x acceleration

Question 5

Newton’s First Law states that

Answer 5

An object will remain at rest unless acted upon by an unbalanced force.

Question 6

Newton’s Second Law states that

Answer 6

The rate of change of momentum of an object or body (or acceleration of an object with a fixed mass) is directly proportional to the force causing the change, and the resultant change in momentum occurs in the direction the force was applied.

In other words F = Mass x Acceleration
