force, mass and acceleration

Back to SCIENCE main page

If the resultant force acting on an object is zero, a stationary object remains stationary. A moving object keeps moving at the same speed and in the same direction.

If the resultant force acting on an object is not zero, a stationary object begins to accelerate in the direction of the force. A moving object speeds up, slows down or changes direction.

Acceleration depends on the force applied to an object and the mass of the object.
