Newtons laws and momentum Flashcards
1
Q
What is linear momentum?
A
mass x velocity
2
Q
What is Newton’s first law of motion?
A
An object will remain at rest or continue to move at a constant velocity unless acted on by a resultant force
3
Q
What is Newton’s third law of motion?
A
When two objects interact, they exert equal and opposite forces on eachother
4
Q
What is Newton’s second law of motion?
A
The resultant force acting on an object is directly proportional to the rate of change of momentum and is in the same direction
5
Q
What is the principle of the conservation of momentum?
A
Total momentum of a closed system remains the same before and after a collision
6
Q
What is an elastic collision?
A
A collision in which kinetic energy is conserved
