Stage 2 Physics - Momentum Pracitcal Investigation
STAGE 2 PHYSICS
Assessment Type 1: Investigation Folio
Practical Investigation 2: Momentum
Purpose:
To investigate the relationship between the laws of conservation of momentum and Newton’s Third Law and another variable of your choice for a 2D collision of two objects.
Materials:
Hover puck
Video Recorder
Tripod
Masking tape
Ruler
Tracker (Computer Program)
Method:
On a flat surface containing no obstacles, prepare the tripod and camera over the selected area that the collision will take place
Align masking tape 45 degrees from each corner as a shown above (the arrows). This can be used as a guide for the person releasing the pucks (Optional step)
Test the camera angle so that it captures the collision and the before and after speeds. Make sure you have enough room for this
Identify and label which puck will be the variable and the one which will be held constant. These pucks must be held constant throughout the entire practical
Have a person ready with the camera, while another aligns the pucks in their initial positions. Once ready, signal the camera person, and record the collision at least 3 times
Repeat collision altering the variable puck in which ever way you have chosen to do. In our case we added 100g of weight each time. Record each change you make and record them at least 3 times each
Analyse the data collected and choose the best video of each variable and begin to import them into the computer program tracker.
Independent and Dependent variable
Independent variable: mass being added to puck b.
Dependent variable: Δp (change in momentum)
Other variables that are held constant in this practical
Mass of puck A - held constant by not altering the weight
Position of camera - held constant by keeping the camera in the same position for each take
Release angle of puck - held constant by repeating the same action for each variable
Safety Regulations
This practical contained considerable risk of
