Newton's 3 Laws of Motion

     The first law says," An object in motion tends to stay in motion, and an object at rest tends to stay at rest, unless acted upon by an outside force." This means that if something is in motion it will stay in motion unless somethings stops it. The second law says," The acceleration of an object is dependent upon the force acting on the object and the mass of the object." This means that how fast something is going depends on the force and the mass of the object. The third law says," For every action there is an equal and opposite reaction." This means that for everything something does there is something else that happens because of it. The picture below is an example of the second law.

Weightlessness is where the weight is undectable. If you're floating in space your weight is undectable.

Newton's Law of Universal Gravitation

Newton's law says that the planets, the stars, and all particles of matter exert a gravitational force. This explaines why the moon orbits around the earth and the earth orbits around the sun. The bigger something is the bigger the gravitational pull is.


Momentum is mass and speed combined. A softball has more momentum than a tennis ball, but a tennis ball has more momentum than a ping-pong ball.
