PPT-GRAVITY

Gravity Gravity is a force that for us is always directed downwards But to say that gravity acts 
downwards is not correct Gravity acts down no matter where you stand on the Earth It is 
better to say that on Earth gravity pulls objects towards the center of the Earth So no matter 
where you are on Earth all objects fall to the ground.

The element of earth was thought to be heavy by nature and therefore pulled towards the centre of the (geocentric) universe.. Big Science: Big Telescopes. Jodrell Bank Discovery Centre. Contents. Part 1: Gravity on Earth. Mass or weight?. The strength of Earth’s gravity. Part 2: Big Telescopes. How do we see space?. Part 3: Gravity in Space. Einstein and Newton. 1. Newtonian Gravity. Newton explains the universe using forces. 2. Newton. Newtonian gravitational theory is based on forces acting on one another.. An object at rest stays at rest and an object in motion stays in motion (in a straight line) until acted upon by another force.. Danielle DelVillano, Pharm.D.. Objectives. Define density, specific gravity, and specific volume and determine each through appropriate calculations. Apply specific gravity correctly in converting weight to volume and volume to weight. EQ: What changes an object’s motion?. Friction and Gravity. What happens when you jump on a sled on the side of a snow-covered hill?. What happens at the bottom of the hill?. Friction and Gravity. Why does the sled’s motion change on the side of the hill and then again at the bottom?. EQ: What changes an object’s motion?. Friction and Gravity.
