Kinetic Friction Experiment
... 3. Place the wood side of the block against the track and add 500 g of mass on top of the friction block. (What is the mass that will now slide along the track?) The block should be at least 30 cm in front of the motion sensor. 4. Attach a pulley as shown in Figure 2. Place the larger area wood sur ...

Action Reaction
... If the wagon pulls harder on the horse than the ground pushes, there is a net force in the backward direction, and the horse accelerates backward. (This wouldn't happen on level ground, but it could happen on a hill...) If the force that the wagon exerts on the horse is the same size as the force t ...

All of the parts of the spinning object are moving in different directions, but the object itself may be stationary. We need a new analysis system to cover items that are spinning about an axis. Rotation is the moti ...

SPH4U: Forces
... Reason. Isaac says, “On the force diagram for moment 3 we should draw an upwards force due to the trampoline since he is still traveling upwards. We should make it smaller than gravity since that force is running out.” Do you agree or disagree with Isaac? Use an interaction diagram to help explain. ...
