Question 1 • 2003390-Physics 1 Honors Sem. 1 - Peters
If it were possible to remove gravity and friction, think about what would happen to a football if it were tossed into the air. Assume the football is in a vacuum (no gravity or friction) and is continuously moving, which force(s) would be acting on the ball?
Answer
A
A force must be applied to it when it slows to a position of rest.
B
A force must be applied to it before it slows to a position of rest.
C
No force is needed; an object in motion stays in motion.
D
Many forces must act upon it to keep it in motion.
