What do unbalanced forces do to an object when they act upon the object?

• unbalanced forces cause an object to maintain its state of motion

• unbalanced forces cause the net force of an object to be zero

• unbalanced forces cause an object to start moving, stop moving or change direction

• unbalanced forces cause an object to maintain the same speed and the same direction

What is one way that kinetic energy is different from potential energy?

• the kinetic energy of an object depends upon the object's height above the ground while the potential energy of an object depends upon the object's motion

• the potential energy of an object depends upon the object's height above the ground while the kinetic energy of an object depends upon the objects motion

• the kinetic energy of an object can change but the potential energy of an object always remains constant

• the potential energy of an object can change but the kinetic energy of an object always remains constant

A squid moves through the water by ejecting water out of its body into the surrounding water. When the water is pushed out, the ejected water pushes back and thrusts the squid forward. Which of Newton's laws of motion best applies to a squid's movement through water?

• 1st law of motion (law of inertia)

• 2nd law of motion (law of force and acceleration)

• 3rd law of motion (law of action and reaction)

• 1st law of motion (law of action and reaction)
