ASTR 1102 Lecture Notes - Lecture 5: Table Tennis, Medicine Ball
Document Summary
Developed universal law of gravity and three laws of motion laws describe motion in our physical world. Object in motion/rest stays in motion/rest unless acted upon by an outside force rocket in space moving forward will continue moving forward. Second law of motion force = mass x acceleration (f = ma) if you flick a ping pong ball it goes across room, but if you flick a medicine ball, it barely moves. Ping pong ball = low mass with high acceleration (low mass always has high acceleration) Massive object will accelerate very little (high mass will accelerate always only a little) To every action, there is an equal and opposite reaction. Whenever one body exerts a force on second body, the second body exerts the same first on the first. Every object attracts every other object with a force that is proportional to the product of the two masses and inversely proportional to square of distance between.
