Momentum and inertia Flashcards
1
Q
What is momentum?
A
Momentum is the product of mass and velocity
2
Q
What is the formula for momentum?
A
Momentum = mass x velocity
P = MV
3
Q
Is momentum constant?
A
Yes
4
Q
How is momentum preserved?
A
The momentum of an object will never change if it is left alone
5
Q
How will a change in momentum occur?
A
A change in momentum will only happen as a result of a change in velocity
6
Q
What is inertia?
A
The resistance an object has to change it’s state of motion
7
Q
How does inertia increase?
A
As mass increases so does inertia
- the bigger the mass of an object the harder it is to move or change it’s motion
