if an object starts to accelerate what is acting on it
Answers
Answer:
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion.
Answer:
Force
Explanation:
When an object begins to accelerate, it means it's velocity changes from zero to a non-zero value and keeps increasing. This is because acceleration means change in the velocity, and velocity can only change when an unbalanced external force is acting on it. According to Newton's First Law of Motion, a body continues to be at rest unless an external unbalanced force acts on it.
Pls note that external unbalanced force means force only.
