Warm-Up & CCA Week 18 Review Jan 13, 2014
During PE the class is split into two groups for a tug-of-war. Group 1 pulls on the rope with a force of 2561 N. Group 2 pulls in the opposite direction with a force of 2516 N. What will be the outcome of the tug-of-war? 2) When a force acting on an object changes the object’s motion, the force is… 3) Place these in order from greatest potential energy to least
You need to know: • Gravity is an invisible force that cannot be seen. Gravitational pull explains why all planets in the solar system orbit the sun • The bigger the planet, the stronger the gravitational pull • Gravity allows the planets to rotate around the sun
SunMercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto The closer the planet is to the sun, the stronger the gravitational pull.
What do you think? • Scientist discover a small planet between Mars and Jupiter. What can the scientist assume about the gravitational pull of the Sun on the new planet? • The gravitational pull will be less than found on Earth
