Net Force Practice

Front

What is net force?

Back

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

Front

What unit is used to measure force?

Back

Force is measured in Newtons (N).

Front

What does it mean for forces to be balanced?

Back

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

Front

What does it mean for forces to be unbalanced?

Back

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.

Front

If an object is at rest and the forces acting on it are balanced, what can be said about its motion?

Back

The object will remain at rest.

Front

If a marble rolls down a ramp, what type of forces are acting on it?

Back

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

Front

What is the net force on an object if 50 N is applied to the left and 30 N is applied to the right?

Back

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

Front

How do you calculate net force when multiple forces are acting on an object?

Back

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

Front

What happens to an object if the net force acting on it is zero?

Back

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

Front

What is the effect of unbalanced forces on an object's motion?

Back

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