Question
A moving object is under the action of ___.
- Wind
- Air
- Pressure
- Force
Hint:
A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate.
The correct answer is: Force
- Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.
- Can change the state of an object.
- May change the speed of an object.
- May change the direction of motion of an object.
- May bring about a change in the shape of an object.
- Air, pressure, wind all these can make the object move by the force they applied.
