Newton and Momentum

Question 1

Newtons First Law of Motion

Answer 1

Every body continues in its state of rest or of uniform motion in a straight line unless acted on by some external force.

Question 2

Define Inertia

Answer 2

The tendency of matter to retain its state of rest or of uniform motion.
(mass)

Question 3

Archimedean Upthrust

Answer 3

Force experienced on object is equal to the weight of fluid displaced.

Question 4

Newtons Second Law of Motion

Answer 4

The rate of change of momentum of a body is directly proportional to the external force acting on the body.
(F=ma)

Question 5

Newtons Third Law of Motion

Answer 5

For every action there is an equal and opposite reaction.

Question 6

Principle of Conservation of Momentum

Answer 6

The total linear momentum of a system of interacting bodies on which no external forces are acting, remains constant.

Question 7

Define Impulse

Answer 7

Impulse is the change in momentum

Question 8

Principle of Conservation of Momentum

Answer 8

The total linear momentum of a system of interacting bodies on which no external forces are acting, remains constant.

Question 9

Define Impulse

Answer 9

Impulse is the change in momentum
