Law of Conservation of Momentum

Coulomb's Law tells us that the closer two oppositely charged objects are, the stronger their attractive force will be. What everyday object can we demonstrate this with?
Magnets
200
What equation is used to solve for momentum?
p=mv
200
The change in an object's momentum depends on the magnitude of the force applied, as well as:
the length of time the force is applied
200
In which type of collision will objects "bounce" off one another, moving separately after the collision?
Elastic
200
What equation do we use to solve for a conservation of momentum problem?
200
In any form of diffusion/particle movement, particles move from areas of ________ pressure/concentration to areas of ________ pressure/concentration
high, low
300
The OFFICIAL unit for momentum (not the one we made up) is what?
kg * m/s
300
What equation is used for the impulse-momentum theorem?
Ft=(delta)mv
300
Why are most elastic collisions not perfectly elastic?
Kinetic energy is often transformed into heat or sound energy
300
Why does it make sense that kinetic energy and momentum are similar?
Both require movement

400
What will cause a change in momentum?
Applied force
400
The unit for impulse is a: (Hint: what do you multiply together to find impulse?)
Newton-second
400
In a perfectly inelastic equation, what will happen to the colliding objects?
They will "stick" together
400
Which of Newton's Laws also describes conservation of momentum?
Third law

Antimatter is composed of antiparticles that share the same mass as their counterparts, but have the opposite charge. What would the antimatter version of the Hydrogen ion be?
H-
500
The momentum of an object is directly proportional to the object's:
mass AND velocity
500
How could a small force result in a large change in momentum?
By increasing the amount of time that force is applied
500
What is different between the equation used in the law of conservation of momentum, and the one used for a perfectly inelastic collision?
Solving for just one final velocity in an inelastic equation

An ice skater in motion collides with another ice skater standing on the ice. What kind of collision would this be?
Inelastic
600
How was the law of conservation of momentum still followed when your eggs collided with the ground?
Momentum was still conserved, however the mass of Earth is so large, we are unable to feel any change in its velocity when small objects collide with it.
