The way in which forces combine depends on...

• the temperature of the environment.

• gravity and air resistance.

• the direction of the forces applied to the object.

• the speed of the objects involved.

When the forces acting on an object are moving in the same direction, the net force is

• the difference of the individual forces.

• zero.

• the sum of the individual forces.

• always equal to the largest force.

Because forces have direction, you have to specify a _____ when you combine forces.

• reference direction

• speed
• number

• mass

Calculate the net force:
