 This law states an object will stay at rest unless an unbalanced force acts on it and an object in motion will continue to move in the same direction and at the same speed unless an unbalanced force acts on it:

• third law of motion
• first law of motion
• inertia
• second law of motion

The unit label for force that we have been using in our f=ma formulas is:

• kg
• N
• m/s

Energy from water comes from....

• atoms
• the water turns turbines which helps to produce electricity
• the uranium gives off a large amount of heat
• the scientists that separate the hydrogen from the oxygen in water
