3.5 Newton's Laws of Motion and Momentum Flashcards
1
Q
when two or more objects collide what is there a transfer of?
A
momentum and kinetic energy, providing there are no external forces acting in the system the total momentum is conserved
2
Q
What does the term perfectly elastic collision mean?
A
The total kinetic energy of a system will remain constant
3
Q
What does the term inelastic collision mean
A
some of the kinetic energy will be lost to other forms
4
Q
What is the formula for one dimensional collisions
A
m1u1 +m2u2 = m1v1 +m2v2
5
Q
What is the formula for two dimensional collisions
A
X direction
m1v0 = m1v1cosx1 + m2v2cosx2
0 = m1v1sinx1 + m2v2 sinx2
