Law 3
400
Which object would require the most force to move?

A soccer ball is at rest on the ground. When a force is applied to it, it moves. If larger force is applied to it, how will the motion of the soccer ball change?
A. The ball will move less distance with less speed.
B. The ball will move farther with less speed.
C. The ball will move farther with more speed.
D. The ball will move less with more speed.
C. The ball will move farther with more speed.
600
How do you calculate speed?
Speed = distance / time
600
The force that acts directly against the direction of motion.

A. Air balances the forces and makes the puck move faster.
B. Air causes the puck to slow down.
C. Air causes the puck to have less mass and travel farther.
D. Air reduces friction and allows the puck to move easily.
D. Air reduces friction and allows the puck to move easily.

Is a bicyclist going who is moving at a constant speed in a figure 8 pattern accelerating?
YES because he is changing direction
(acceleration is any change in speed and/or direction)
