COMPARING INTERACTIONS - LAB
Differentiate electromagnetic and gravity interaction.
Describe 4 interactions.
Compare electromagnetism with
Gravity has to do with motion.
A physicist may define forces
as mass times acceleration. A force that acts on a body which is free
to move, produces an acceleration in the motion of a body, measured by
the rate of change of the momentum of a body. In this case force is
treated mathematically, however forces also refer to a fundamental
notion of motion.
This portion of the lab will focus on
mechanics. In this lab, there will be different gadgets around the
room in stations, and the students will have to decide how to explain
why that gadget works. You will have to discuss friction, gravity,
buoyancy, action/reaction, inertia, and any other force that will
describe the gadgets listed below in the procedure.
meter, slinky, force machine, small rubber balls, magnets, alien ball,
jacobs ladder, density timers, immersed hourglass
Drinking Duck: changing pressure in bulb
Love meter: changing pressure in bulb
Slinky: spring, gravity
Force machine: action – reaction forces
Small rubber balls – gravity
Alien ball- electricity, light, sound
Jacobs ladder – gravity, friction
Density timers – gravity
