Jose pushes a box 3.0 m by applying a force of 200 N onto it.
How much work has he done?
W = Fapplied * displacement
W = 200N * 3.0m
W = 600J
Jose has done 600J of work
How much energy did Jose need in order to do this work?
Jose needed 600J of ener
A force of 250 N is used to push a heavy box down the street. If the force of
friction between the box and the street is 195 N and the box has a mass of
60 kg, what is the acceleration of the box?
Fnet = Fapplied Ff
Fnet = 250n 195n
Fnet = 55n
Gravity causes objects to be accelerated towards the ground. To see evidence of
this, you need only push a pencil off the side of your desk. In this lab activity, you
will use a multimedia element to assist you in determining the rate at which
Purpose: To determine if the given resistors are Ohmic and to determine their resistance.
Resistor # 1: brown, black, brown, silver (100 10%)
Resistor # 2: blue, grey, black, gold (68 5%)
Bouncing Ball: Impulse Vs. Height
Research question: What is the mathematical relationship between drop height of a ball
and impulse of that bouncing ball?

Collisions are common occurrences in everyday life. The ball striking the table is a form
of a collision. During a collision, the force usually jumps from zero at the moment of
contact to a very large force within a very short time, and then rapidly retur
When the current readings from the multimeter are plotted against the voltage
readings, a linear slope can be constructed. The slope of the current vs. voltage graph
indicates the resistance value for that specific resistor. The uncertainty of the resista
