changes.
Illustrate

balanced forces and a picture that
represents unbalanced forces.
 Identify
a situation involving unbalanced
forces. Describe net force, and explain how


A car turns right without slowing down.
A spacecraft moves in one direction at a
constant speed.

Arrange
the following pairs
in order of most friction to

 A shoe sole and the sidewalk
Define
State
gravity
Newton’s
Three Laws of Motion
– give an example of
each.
Remember
acceleration is the
change in velocity. To calculate
acceleration you subtract
beginning velocity from ending
velocity and then divide that by
period of time.
So,
calculate the following:
 What
is the acceleration of a car that
starts from rest (0 m/s) and moves
straight ahead at 18 m/s in 12 s?
Compare and Contrast
