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
gravity cau

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
Jose pushes a box 3.0 m by applying a force of 200 N onto it.
How much work has he done?
1.
W = Fapplied * displacement
W = 200N * 3.0m
W = 600J
Jose has done 600J of work
2.
How much energy did Jose need in order to do this work?
Jose needed 600J of ener
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

The purpose of this investigation was to attempt and visualize uniform acceleration while
a cart is travelling down an inclined plane.

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?

In addition, the mass of the clippers that were hung down the string were not massed
properly. In order to save time and share the only electronic balance, only the first four
clippers were massed. Every time, we placed four more clippers to different tri
The percentage error for this lab is great due to many human errors. First of all, the
radius of the circle was not controlled properly. A tape was used to stop the string from
moving beyond the planned radius length; however as the velocity of the spinni

Conclusion:
Often in physics, the effects of air resistance are ignored for the sake of
convenience. However, air resistance does exist in reality and is sometimes referred to as
the drag force. When an object moves through air, the drag force causes the
