Net Force Worksheet - self check

Front

What is net force?

Back

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

Front

How do you determine the direction of net force?

Back

The direction of net force is determined by the direction of the greater force acting on the object. If forces are balanced, the net force is zero.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

If two forces act in opposite directions, how do you calculate the net force?

Back

To calculate the net force, subtract the smaller force from the larger force and take the direction of the larger force.

Front

What is the net force when 5 N to the left and 1 N to the right are acting on an object?

Back

The net force is 4 N to the left (5 N left - 1 N right = 4 N left).

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 remain at rest or continue to move at a constant velocity.

Front

What is the relationship between net force and acceleration?

Back

According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

How does increasing mass affect net force if acceleration is constant?

Back

If acceleration is constant, increasing mass will require a greater net force to maintain that acceleration.

Front

What is the net force if 6 N to the left and 1 N to the left are acting on an object?

Back

The net force is 7 N to the left (6 N left + 1 N left = 7 N left).

Front

What is the net force if 4 N to the left and 4 N to the right are acting on an object?

Back

The net force is 0 N (4 N left - 4 N right = 0 N).
