This was a ppt created for one of my college courses that was towards the grade level I was currently teaching. I decided to do it on Newton which is a scientist we study for 5th grade. We had to upload to a Web 2.0 technology called Voice Thread.

• Newton sat under an apple tree one day exploring his new ideas about force and motion. Newton stated that that a force called gravity caused the Earth and the apple to attract each other.
• For example, the Sun’s gravity keeps all the planets in orbit. Also, the Sun’s gravity keeps the Earth in orbit, as the Earth keeps the moon orbiting around it.
• A marble will remain at rest unless an outside force acts on it- boy. An train in motion will until an outside force acts on it- brakes.
• The more force the batter uses, the faster the ball accelerates. Race car drivers put in powerful engines to give it more force.
• The rocket exerts fuel and force to launch but at the same time, Earth’s gravity is pulling it down. The water exerts an equal force but in the opposite direction-pushing the boat forward.
• ### Sir Issac Newton

1. 1. Sir Isaac Newton (1642-1727)
2. 2. *Then all of a sudden ithit him and this ideabecame known asGravity!*Gravity causes theEarth & the apple to beattracted to oneanother.
3. 3. Gravity: the force that pulls allobjects in the universe toward oneanother. Solar system  Sun-Earth-Moon System  Model
4. 4. 1st Law of Motion:an object at rest will remain at rest, and an object inmotion will continue moving in a straight line at a constantspeed until an outside force acts on it.
5. 5. 2nd Law of Motion:an object’s acceleration depends on the sizeand the direction of the force acting on it andthe mass of the object.
6. 6. 3 rd Law of motion:for every reaction, there is an equal andopposite reaction.
