Momentum equations Flashcards
1
Q
What is the equation for momentum?
A
p=mv
momentum (kg m/s) = mass (kg) x velocity (m/s)
2
Q
Like the rule for momentum
What is the principle of conservation of momentum?
A
The total momentum before a collision= the total moment after a collision
3
Q
What is the equation for the relationship of force and momentum?
A
Force(N)= change in monetum (kgms-1)/ change in time (s)
4
Q
What is newtons third law?
A
When two objects interact the forces they exert are equal and opposite.
The amount of force can be equal but the direction can be opposite
5
Q
What si teh equation for impact force?
A
change in momentum=mu-mv=force x change in time
