Momentum and Impulse

Question 1

Momentum, what is it

Answer 1

It is the product of Mass and Velocity

Question 2

Is Momentum a Vector or a Scalar

Answer 2

Momentum is a Vector

Question 3

What is the Formula for Momentum

KG.M.S-1

Answer 3

p=m*v
p-Momentum
m-Mass
v-Velocity

Question 4

What is impulse

Answer 4

It is the change in Momentum
OR
Product of the net force acting on an object and the time the net force acts on the object.

Question 5

What is the formula for Impulse

Answer 5

Impulse=Momentum

Impulse=Mass*(Vf-Vi)

Question 6

What is Newtons Third Law

Answer 6

If A exerts a force on B, B then exerts an equal on force A
OR
A on B=B on A

Question 7

What is the principle of conservation of linear momentum

Answer 7

Total linear momentum in an isolated system remains constant

Question 8

Formula for Two objects that separate after collision

Answer 8

(M1)(V1)+(M2)(Vi)
=
(M1)(Vf)+(M2)(Vf)

Question 9

Formula for Two objects that couple after collision

Answer 9

(M1)(Vi)+(M2)(Vi)
=
(M1+M2)(Vf)

Question 10

Formula for Two coupled objects that separate after an explosion

Answer 10

(M1+M2)Vi
=
(M1)(Vf)+(M2)(Vf)

Question 11

What is an Elastic collision

Answer 11

A type of collision where kinetic energy is observed.
Kinetic energy before
=
Kinetic energy after

Question 12

What is an Inelastic collision

Answer 12

A type of collision where Kinetic energy is not conserved.
