No, lots of forces act on an object.
The only force acting on an object in freefall is gravity. This force causes the object to accelerate downward towards the Earth.
gravity
Friction slows down the motion of an object when it is the only force acting on it. It opposes the object's movement, causing it to eventually come to a stop.
Gravity.
Gravity must be the only force acting on the object.
Gravity.
free fall
When only one force is acting on an object, the object will accelerate in the direction of that force following Newton's second law (F=ma). The object will either speed up, slow down, or change direction depending on the direction and magnitude of the force.
Work is defined as the product of force and displacement. If an object is not in motion, there is no displacement, thus no work is done by the force acting on the object. Work is only done when a force causes an object to move through a distance in the direction of the force.
True (:
The two states that exist when the only force acting on an object is gravity are free fall and equilibrium. In free fall, the object is accelerating downward due to gravity, while in equilibrium, the object is either at rest or moving at a constant velocity with no net force acting on it.
