Model gravitational and spring forces experimentally
How does weight (gravitational force) depend on mass and the local gravitational field?
Determine the relationship between the stretch displacement of your spring and the force that is used to stretch the spring.
Water skiers are pulled at a constant speed by a towrope attached to a speedboat. Because the weight of the skiers and the type of skis they are using varies, they experience different resistive forces from the water. Values for this resistive force (RF) and for the speed of the skiers are given.

Rank the tension in the towrope. Explain your reasoning

Sharon Steady and Al Wayskachon won South’s recent egg toss contest held during Homecoming week. In their winning toss, Sharon gave the egg an underhand toss, releasing it with a velocity of 7.5 m/s at an angle of 30° to the horizontal. To the pleasure of the crowd, Al caught the egg at the same height as the toss without even a fracture to its shell.

We will use the same steps for every correction:
Think clearly, show your physics, learn deeply
Car A is traveling to the right at a constant velocity
time it takes Car B to catch up top Car A?

A.
D. It cannot be determined without knowing the distance traveled by the cars
Car A is traveling to the right at a constant velocity

On the same axes, sketch the velocity graphs for each car. Label any important velocites or times.

In each case shown, someone is running on a flatbed train car as the train moves. In cases C and D, the person is running toward the front of the train, while in cases A and B the person is running toward the rear. The speeds of the train and of each person relative to the train are given.

Rank the speed of the runners relative to the observer standing beside the tracks.

Shown below are the paths two motorcyclists took on an afternoon ride. Both started at the same place, and both took the same time for the ride. Rider A traveled east for 19 km and then south for 4 km. Rider B traveled south for 7 km and then east for 16 km.

Is the magnitude of the displacement of the rider (i) greater in case A, (ii) greater in case B, or (iii) the same in both cases? Explain your reasoning.
