1. 8th grade warm ups for Week of 12-4-17

2. Monday (Mon.)
EQ: How are balanced and unbalanced forces related to an object’s motion?
WU: What does an object have to have in order to move?
Ans: In order for an object to move it must have an unbalanced force, which is a push or pull, applied to a object.

3. Tuesday (Tues.)
WU: What is the result of an unbalanced force acting on an object?
Ans: Unbalanced force cause a change in the object’s motion. It travels in the direction of the stronger force.

4. Wednesday (Wed.)
WU: What happens to an object’s motion when the forces acting on it are balanced?
Ans: When balanced forces act on an object, the object does not move.

5. Thursday(Thurs.) 12-7-17 EQ: How is friction useful?
WU: In what direction does friction act?
Ans: 1: Friction always acts in the opposite direction in relationship to the direction the object is moving.
2: Ex: 1: a rolling chair—you push out/forward to go back. 2: mowing your yard

6. Friday (Fri.) 12-8-17 WU: What factors determine
the strength of the friction force between two surfaces?
Ans: The strength of the friction force depends on how hard the surfaces push together and the type of surfaces involved.
