If you catch a baseball, your hand might sting, even if you use a baseball glove. Why does your hand sting?
You have weak hands
The baseball exerted a force on your hand when it came to a stop, and its momentum changed
It's a chemical reaction
Fossil Fuels in the baseball burned when it hit your hand
How can net force exerted on an object be calculated?
Multiplying its change in momentum by the mass of the object
Multiplying length, width, and height together
Subtracting time from velocity
Dividing its change in momentum by the time over which the change occurs
What would happen if two air hockey pucks of equal mass were moving toward each other with the same speed?
they would have the same momentum and go the same direction
they would have the same momentum, but in go opposite directions
they would have a different momentum, but go in opposite directions
they would have different momentum and go the same direction
What is transferred in collisions?
momentum
speed
velocity
rate of acceleration
What do the results of a collision depend on?
weight transfer
mass
acceleration
momentum of each object
How is Newton's second law written?
F = (mvf - mvi) / t
F = mvf / t
F = (mvi x mvf) + t
F = (mvf + mvi) - t / s
