Momentum

Question 1

What is the equasion for momentum?

Answer 1

p = mv (mass x velocity)

Question 2

When is momentum possitive or negative?

Answer 2

If an object is travelling to the left it has a negative momentum. If it is travelling to the right it has a possitive momentum.

Question 3

What does magnitude refer to?

Answer 3

Question 4

What is the law of conservation of momentum?

Answer 4

Momentume befire = momentume after

Question 5

How to calculate force from momentum

Answer 5

F = change in momentum
———————————-
Time taken

Question 6

What does hooke’s law state?

Answer 6

The extension of an elastic object is directly proportional to the force applied, up to the limit of proportionality

Question 7

What does it mean when an object is inelastically deformed?

Answer 7

It mesns that the object of stretched byeong its limits and will not go back to its original shape when the force is removed.

Question 8

What is hook’s law equasion

Answer 8

F = k x e
(Force = Spring constant in newtons per metres (N/m) x extension (m))
