Question

What is a cause of a change in the velocity of an object moving? (Choose 3 points, all that apply)

A. The object has a force acting upon it from a different direction than it is going.
B. The object has a force acting upon it from the opposite direction it is going.
C. The forces acting on the object remain unchanging and constant.
D. The object has a force acting upon it in the same direction it is going.

Answer 1

A cause of a change in the velocity of an object moving can be a force acting on it from a different direction, a force acting on it from the opposite direction, or a force acting on it in the same direction.

Step-by-step explanation:

When an object is moving, there are three possible causes for a change in its velocity:

• A: If the object has a force acting upon it from a different direction than it is going, the velocity will change due to the net force applied in a different direction.
• B: If the object has a force acting upon it from the opposite direction it is going, the velocity will change because the force is opposing the motion.
• D: If the object has a force acting upon it in the same direction it is going, the velocity may change because the force can either speed up or slow down the object depending on the magnitude of the force.
