The force must be in the same direction as the object’s motion
Explanation:
Force is a physical quantity.
It is defined as the force applied to a body to move it in the direction of the force applied.
Force = mass x acceleration.
- Force results in the acceleration of a body.
- Force causes the change in position of a body and it moves it towards the direction of the applied force.
- A force is a vector quantity having both magnitude and direction.
So, option is C is the correct choice.
