Lesson 2
By Logan VanderPlaats
Newtons law of universal gravitation
According to this law everything has gravitational farce. This explaines the moons orbit arrount earth. this changed the way scientists look at the solar system.
Momentum
Momentum is the objectsmass and speed.Momentum does not change when objects collide.An object with more momentum is harder to stop.
Weightlessness
Astronauts in an orbiting space ship feel the same way a falling skydiver feels. In space if you are weightless you still have the same mass.
Newtons 3rd law of motion
For every action there is an equal and oppisite reaction. If you dribble a basketball the ground pushis it up with the same force.
