Formula
momentum
p=(m)(v)
Energy
The ability of an object to produce a change in itself or in the world around it.
For any object to have momentum, what two properties must it have?
velocity & mass
momentum
kg.m/s
TV is an example of what energy transformations.
electricity to light and sound energy
mass
m=p/v
Work
Measure of energy transfer that occurs when a object id moved over a distance.
In order to slow down or stop an object with momentum, you must exert ________ on the object.
force
velocity
m/s
velocity
v=m/p
Energy which a body possesses by virtue of being in motion.
What is the difference between momentum and impulse?
In order for there to be impulse a force needs to be acting on an object for a time interval, while momentum requires a certain amount of mass/velocity.
mass
kg
impulse
j=(f)change in(t)
Potential energy
The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
How is the change in momentum determined?
through initial and final velocity
impulse
n/s
conservation of momentum
M(a)V(a)-M(b)V(b)
Momentum
Ultimately describes the motion of an object.
A beach ball is rolling in a straight line toward you at a speed of 0.5 m/sec. Its momentum is 0.25 kg.m/sec. What is mass of the beach ball?
0.5 kg
net force
