Question

practice it!
which statement(s) describe how forces influence motion?
a force can change the direction of motion.
a force can stop motion.
a force can speed up or slow down motion.
a force can start motion.
a force can change the power of the force.

Explanation:

According to Newton's laws of motion, a force can change the direction of motion (e.g., a ball being hit and changing its path), stop motion (e.g., a frictional force bringing a sliding object to rest), speed up or slow down motion (e.g., a car accelerating or decelerating due to engine force or braking force), and start motion (e.g., pushing a stationary box to make it move). However, a force cannot change its own power; the power of a force is determined by external factors.

Answer:

A. A force can change the direction of motion.
B. A force can stop motion.
C. A force can speed up or slow down motion.
D. A force can start motion.
