Forces and Acceleration

Forces that are equal in size but opposite direction are called unbalanced forces.

• True

• False

Forces that are unequal in size where the applied force of one object is greater than the other object's force are balanced forces.

• True

• False

Balanced forces acting on an object cause the object to acclerate

• True

• False

If a net force acts on an object, the object may change speed, change direction or do neither.

• True

• False
