The Laws of Motion
Second law: Only unbalanced forces cause an object to accelerate. Equation: acceleration= force divided by mass
Third law: It's sometimes call the law of action and reaction. For every action, there's an equal and opposite reaction.
Momentum can be used to find the force needed to stop an object. An object momentum depends on it's mass and velocity
First law: This law is sometimes called INERTIA. INERTIA is the tendency of an object to remain at rest unless a force acts on it.
Gravitational Force
It's the force of attraction between any object and every other object in the universe and depends on MASS and DISTANCE.
Gravity and the Universe
Planets in our solar system have less mass than our sun. So there's less effect on the sun's motion, but in other universe, mass of there planet and star are much closer. This will cause stars to WOBBLE.
Astronomers use this WOBBLE to locate stars.
