Objective 2 Examine the force exerted on objects by gravity
... The structure needs to have enough support to hold the building and objects in it up (& not crash down). 14. What is a net force? The total sum of all forces. 15. Give an example of friction in action: When an object moves past another object and slows the moving object down 16. Why does the moon ne ...

... watching the girls on the swings, the trees and ground would help you determine that the girls were changing their position. You can tell the difference between a moving object and one that's still. But how would you define motion? An object is in motion when its position changes. Position is the lo ...

... 15. REASONING AND SOLUTION The amount of force F needed to stretch a rod is given by Equation 10.17: F Y( L / L0 )A , where A is the cross-sectional area of the rod, L0 is the original length, L is the change in length, and Y is Young's modulus of the material. Since the cylinders are made of t ...

How fast does the sled then move? 3) Two people, one of mass 75 kg and the other of mass 60 kg, sit in a rowboat of mass 80 kg. With the boat initially at rest, the two people, who have been sitting at opposi ...
