| What is the equation for slope? | Rise ÷ Run |
| The force of gravity on a person or object at the surface of a planet is known as... | weight |
| How can you tell if an object is in motion? | If the distance between an object and its reference point changes. |
| What causes your weight to be different on every planet? | Gravity |
| You and your friends need to push a Smart Car that is 7154N and a truck that is 23,000N at the same speed, which vehicle would you have to push with more force? | Truck |
| The force of gravity depends on... | Mass and Distance |
| The density of a sample of a substance is 80g/cm³, and its mass is 160 grams. What is the volume of this sample? | 2 cm³ |
| What is the density of a solid 1cm long, 0.5cm wide and 2cm high, if the mass is 6 grams? (remember volume is length x width x height) | 6 g/cm³ |
| A student has two containers. Container A holds one liter of liquid. Container B holds two liters of liquid. Both containers are filled with the same liquid.What statement would be true about cantainer A and caontainer B. | The density of the liquid in container A is equal to the density of the liquid in container B. |
| How do snowshoes make it easier to walk on snow | Snow shoes increase surface area which spreads out the amount of force you put on the snow. |
