1) If a spaceship is traveling in a straight line way out in space (far away from any planets), will it ever slow down? Why or why not? Which of Newton’s laws explains this?
2) If Newton’s first law says that objects in motion will stay in motion, then why do things slow down when we push them?
3) If a book sits on a table, the force of gravity pulls down. If there is a force on the book, why doesn’t it move?
4) If I can travel 100 m in 4 s, what is my velocity?
5) If I am driving at a velocity of 25 m/s, and I increase my velocity to 50 m/s in a period of 8 s, what is my acceleration?
6) If I push on a 10 kg block with a force of 8 N, what is the acceleration?
7) If I push on an object with a force of 18 N, and it accelerates at a rate of 2 m/s2, what is the object’s mass?
4) What is the difference between mass and weight?
5) If you take an object to the Moon, will its mass be the same as it is on Earth? Will its weight be the same?
6) Which object would accelerate more: a big one or a small one?
7) Describe Kepler’s First Law
8) Describe Kepler’s Second Law
