... 1) A cave dweller rotates a pebble in a sling with a radius of .30 m counterclockwise through an arc length of 0.96 m. What is the angular displacement of the pebble? 2) What is the approximate angular speed of a wheel rotating at the rate of 5.0 rev/s? 3) A grinding wheel initially at rest with a r ...

Goal #2 – Motion and Forces
... If the net force on the object is zero, then all the forces are balanced, and the object will not change its motion. (3rd Law) When one object exerts a force on another object, the second object exerts an equal but opposite force on the first object. (Action-reaction) As an object falls freely, if w ...
