Question

Why is change in speed

Answer 1

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

Answer 2

Why is change in speed?

• Speed change because of the way things move is influenced by forces. They can cause motion, as well as delay, stop, or modify the direction of motion of an already moving item. We can say that forces produce velocity changes because they cause changes in the speed or direction of an object. Keep in mind that acceleration is a velocity change.
