Understanding Forces

What happens when you and a friend push a table in the same direction?

• The table does not move at all.

• The table moves more easily.

• The table moves in the opposite direction.

• The table becomes harder to move.

If two equal forces act in opposite directions on an object, what is the net force?

• Equal to the sum of the forces.

• Zero.

• Equal to the product of the forces.

• Equal to the difference of the forces.

When forces act in the same direction on an object, how is the net force calculated?

• By dividing the larger force by the smaller force.

• By adding the magnitudes of the forces.

• By subtracting the smaller force from the larger force.

• By multiplying the forces.

What is the sign convention used when adding forces?

• All forces are considered negative.

• All forces are considered positive.

• Forces to the right are positive, and forces to the left are negative.

• Forces to the right are negative, and forces to the left are positive.

What determines the direction in which an object at rest will move?

• The direction of the initial push.

• The direction of the larger force.

• The direction of the smaller force.

• The direction of the net force.
