Day 7 - Conservation of Energy

Question 1

Energy can’t be created nor destroyed but it can be transformed from one form to another

Answer 1

Law of conservation or energy

Question 2

This force can be expressed in terms of PE function

Answer 2

Conservative Force

Question 3

This forces are non-reversible and there is loss of energy when added

Answer 3

Non-conservative Force

Question 4

What is the formula of Energy Conversion?

Answer 4

mgh=1/2mv^2

Question 5

This is the tendency to remain in motion
m x v
P or rho or kg*m/s

Answer 5

Momentum

Question 6

This is the change in momentum.

I = m(Vf-Vo)

Answer 6

Impulse

Question 7

This type of collision is when KE is conserved.

Answer 7

Elastic

Question 8

This type of collision when it looses some of KE

Answer 8

Inelastic Collision

Question 9

When an object stick together and it loses KE completely

Answer 9

Perfectly Inelastic Collision
