Calculating Net Force

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

Front

What unit do scientists use to measure force?

Back

Newtons (N) are the standard unit of measurement for force in the International System of Units (SI).

Front

A force is described as...

Back

A force is described as a push or pull that can cause an object to move, stop, or change direction.

Front

If two forces of 10 N to the left and 20 N to the right are acting on an object, what is the net force?

Back

The net force is 10 N to the right (20 N right - 10 N left = 10 N right).

Front

What happens when the net force on an object is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant velocity.

Front

What is the formula to calculate net force?

Back

Net Force (F_net) = Sum of all forces acting on an object.

Front

If a 50 N force pulls to the right and a 30 N force pulls to the left, what is the net force?

Back

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

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

Front

What is an example of a balanced force?

Back

An example of balanced forces is when two people push on a stationary object with equal force in opposite directions.

Front

How do you determine the direction of net force?

Back

The direction of the net force is determined by the direction of the larger force acting on the object.
