Stationary

A stationary object remains at rest if the total forces acting on it are zero. When a resultant force is applied, the object will accelerate in the direction of the force.

What condition must be met for a stationary object to remain at rest?

• The object must be in motion.

• The object must be accelerating.

• There must be a resultant force acting on it.

• The sum of the forces acting on it must be zero.

If the forces acting on an object are balanced, what is the object's state?

• It will remain stationary.

• It will change direction.

• It will move in a circular path.

• It will accelerate.

What is the effect of a zero net force on an object?

• The object will change its direction.

• The object will accelerate.

• The object will remain at rest or move with constant velocity.

• The object will decelerate.

What happens to a stationary object when a resultant force acts on it?

• It remains at rest.

• It moves in the opposite direction of the force.

• It starts to accelerate in the direction of the force.

• It decelerates.

Which of the following is true about a resultant force?

• It causes an object to accelerate.

• It decreases the speed of an object.

• It has no effect on an object's motion.

• It causes an object to remain stationary.
