An object is seen to either speed up, slow down, or change direction.
What are these behaviors caused by?
1 answer
These behaviors are caused by forces acting on the object. When an object speeds up, it is typically due to an applied force in the same direction as its motion. When an object slows down, it is usually because there is a force acting in the opposite direction to its motion, which results in a deceleration. Changing direction is caused by a change in the net force acting on the object, which can occur when the direction of the applied force or the direction of the opposing force changes.
