U1.7 Momentum And Impulse Flashcards
1
Q
Is momentum a vector or a scalar
A
Momentum is a vector
2
Q
What is the principle of conservation of linear motion
A
In any interaction between objects their total momentum remains constant, provided no external forces acting the objects
3
Q
What is the definition of impulse
A
The product of the force acting on an object and the time for which it acts
4
Q
What does the area under a force time graph equal
A
The impulse of the force

Elastic collision
6
Q
What type of collision is KE not conserved in
A
Inelastic collisions
7
Q
If two objects stick together in a collision what is it said to be
