Bell Ringer: A group of students are dragging a block with a constant speed across the same surface used in Experiment 3. Its contact area is twice that of Side B and the load is 3.58 N. Use the results of Experiment 3 to predict the force that must be applied to the block. a N b N c N d N
Experiment 3
Another student makes an effort to determine if the area of contact between the block
and the table affects the amount of friction. The scientist finds a rectangular block with
three unequal length sides.
The three areas of the face of the block are:
The student pulls the block (without the sandpaper) along each of the sides at a constant speed. The data are shown in Table 3.

Bell Ringer: 1. During the Egg-Throwing Demonstration in the video, what was the momentum of both eggs before they collided with the sheet or wall if both eggs had a mass of .015 kg and a velocity of 4m/s?
2. Which egg experienced the greater impulse, the egg that hit the wall or the bed sheet? (Be careful here!) Which egg experienced the greater force of impact? Which egg experienced the greater time of impact?
Why?

Which statement is consistent with the data collected in Experiment 1 and Experiment 2?
a. A greater contact area between block and surface results in greater friction force.
b. Changing the contact area has little to no effect upon the amount of friction force.
c. Varying the mass of the block does not have any effect upon the amount of friction.
d. For the same load, a sandpaper surface causes more friction than a plain wood surface.
Experiment 1 Diagram 1 depicts a procedure that is used to measure the friction force. A horizontal force is applied to a block on a table to accelerate it from rest. One observes that the force needed to initiate the motion (accelerate it from rest) is greater than the force needed to sustain the motion at a constant speed. Masses can be added to the block, thus increasing the load (L). The force required to initiate the motion is equal to the static friction force (Fstatic). The force required to sustain the motion at a constant speed is equal to the kinetic friction force (Fkinetic). Table 1 represents typical data from such an experiment.
Experiment 2 - A student decides to investigate the effect of the surface on the amount of friction. She
layers the bottom of the block with coarse sandpaper and then repeats the procedure described in
Experiment 1. Her data is shown in Table 2

39. As I'm sure you suspect, momentum in physics is different from "momentum" in sports on tv, as in "Yes, Chris, the Bengals really have momentum on this drive!". However, physics momentum is related to football momentum in that both concepts refer to how difficult it will be to stop something.What makes an object difficult to stop? Its mass, for one thing. After all, mass measures the inertia of an object - how much the object resists accelerating. Certainly, more mass means more momentum - the momentum of an object is directly proportional to its mass. Twice the mass means twice the momentum. Momentum is not the same as mass, though. For one thing, an object that is not moving has no momentum, no matter how much mass it has.Fast objects are also difficult to stop. Bullets have a very small mass, but you wouldn't want to try and stop one! More speed means more momentum - momentum is directly proportional to velocity. Twice the speed means twice the momentum.Since the momentum of an object is directly proportional to both its mass and its velocity,Momentum = (mass)(velocity) = mvMomentum is a vector quantity. Its direction is the same as the direction of the object's velocity.  M
