Work and Energy
Chapter 7
Work
Work = Force X distance
W = F/ d
W = F d cos
Units: Joules
A person pulls a 50-kg crate 40 m using a force of 100 N at 37.
How much work is done?
m = 15 kg h = 10 m
How much work does the hiker do on the backpack?

Momentum
Momentum = mass X velocity
A force is required to change the
momentum.

Ball has v = 55 m/s and
m = 0.06 kg
It is in contact with
the racket for 4 ms
Estimate average force on the ball

Gravitation and Newtons
Synthesis
Chapter 6
The force of gravity always acts toward
the center of the earth.
Newtons Universal Law of
Gravitation
If gravity acts on objects that are close by,
does gravity also act on objects far away,
such as the moon?

st
Every object continues in its state of rest,
or of uniform velocity in a straight line, as
long as no net force acts on it.
Often called the law of Inertia.

Conservation of Energy
Chapter 8
A force is a conservative force if the work done by the force on
an object moving from one point to another depends only upon
the initial and final positions of the object and is independent
of the path taken.
A force is c
