Question

In which direction would a force need to be exerted to make the object slow down? In which direction would a force need to be exerted to make the object speed up?

Options:
A. Slow down: Opposite direction of motion, Speed up: Same direction of motion
B. Slow down: Same direction of motion, Speed up: Opposite direction of motion
C. Slow down: Perpendicular to motion, Speed up: Opposite direction of motion
D. Slow down: Opposite direction of motion, Speed up: Perpendicular to motion

Answer 1

To make an object slow down, a force is exerted in the opposite direction of motion, while to make an object speed up, a force is exerted in the same direction of motion.

In order to make an object slow down, a force would need to be exerted in the opposite direction of motion. This means that the force would act against the direction the object is currently moving.

To make an object speed up, a force would need to be exerted in the same direction of motion. This means that the force would act in the direction the object is currently moving.
