Momentum

Question 1

Define Momentum

Answer 1

Momentum is the product of mass x Velocity

Question 2

What is the equation for momentum

Answer 2

Momentum= Mass(Kg) x Velocity (ms)
P=MV

Question 3

What is said about Momentum and change of Momentum

Answer 3

-The momentum of an object will never change if it is left alone (momentum is preserved) unless it is interfered with.
-Momentum is Constant
- if Mass and Velocity value remains the same Momentum will remain the same

Question 4

When do changes to momentum happen?

Answer 4

Changes in momentum will only happen as a result of change in velocity
(Acceleration or deceleration caused by an external force)

Question 5

Define Inertia

Answer 5

The resistance an object has to change its state of motion

Question 6

what does an increase of mass do to inertia

Answer 6

inertia will increase as mass increases
- The bigger the object the harder it is to overcome its inertia
- Greater the mass greater the force needed to overcome it
