Question

what is effect changes in speed , direction and velocity?
​

Answer 1

answer:

forces affect how objects move.

they may cause motion;they may also be slow,stop, or change the direction of motion of an object that is already moving.

since force causes change in the speed or direction of object, we can say that force causes change in velocity.

Answer 2

Explanation:

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.
