4. Perform the following task. Stand so that you are facing a wall. Position your feet so that your toes are touching the wall where it meets the floor. While maintaining this position try to go up on your toes ("tip- toe" style). Describe what happens. Discuss rotation. 5. Repeat the above procedure away from the wall and (hopefully) success is achieved. What changed? Pay attention to how your body moves.

The energy a body has by virtue of its motion is known as .

A diver climbs up the ladder of a diving tower. The work they do climbing the ladder is

30⁰ Given: Using the provided information, compete the following problems. NOTE: Find: The system shown is initially in static equilibrium and motionless. Submitted responses shall be to 4 significant figures. Do NOT use scientific notation. 1. The maximum magnitude of the Weight-W that will not initiate motion is 2. The minimum magnitude of the Weight-W that will not initiate motion is 3. Assume the 50LB-Block is on the verge of moving up the inclined plane. The magnitude of internal force in the rope (near the 50LB-Block) is 4. Assume the 50LB-Block is on the verge of moving down the inclined plane. The magnitude of internal force in the rope (near the 50LB-Block) is 50 lb Hs=0.30 W H, = 0.20 LB. LB. LB. LB.

I. General setup - 0.5 m Object of known size (e.g., piece of paper) String Nut / Object II. Prediction questions and background physics For this experiment, you will release the object from rest and observe its subsequent motion. Before conducting the experiment or doing your analysis, answer the following questions based on your understanding of the physics of motion and conservation of energy:
