Net Force Practice

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Force is measured in Newtons (N).

Forces are balanced when the total net force acting on an object is zero, resulting in no change in motion.

Forces are unbalanced when the total net force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

The object will remain at rest.

The forces acting on the marble are unbalanced, causing it to accelerate down the ramp.

The net force is 20 N to the left (50 N left - 30 N right = 20 N left).

To calculate net force, sum all the forces acting on the object, taking into account their directions.

If the net force is zero, the object will either remain at rest or continue to move at a constant velocity.

Unbalanced forces cause an object to accelerate, changing its speed or direction.
