| Questão | Responda |
| Gravitational Potential Energy - what does it depend on? | depends on height, mass, strength of gravitational field |
| Conversion from km/h to m/s | km/h to m/s = divide by 3.6 m/s to km/h = times by 3.6 |
| Delta change and Sum of the change symbols | Delta change = triangle Sum of the change = the weird E thing |
| Newtons Third Law | To every action there is an equal and opposite reaction |
| Mass, weight and gravity definitions | Mass: a measure of the amount of matter in an object MASS DOES NOT CHANGE AS A SUBJECT MOVES THROUGH A UNIVERSE Weight: a measure of the force due to gravity on an object WEIGHT DOES NOT VARY THROUGHOUT THE UNIVERSE Gravity: pulls things around the sun GRAVITY GETS LESS AS YOU MOVE FURTHER AWAY FROM A PLANET OR MOON |
| Newtons Second Law - definition and equation | The size of the acceleration depends on the mass of the object and the size of the force. "A net external force acting on a mass will result in it being moved" F=ma |
| Newtons First Law (Inertia) | Every object continues in its state of rest or uniform motion until acted upon by and external unbalanced force "things keep going until an unbalanced force acts upon it" |
| Efficiency equation | Efficiency = useful energy output/total energy output X 100 (usually as percentage) / = divide by |
| Chemical and Elastic Potential Energy definitions | Chemical: energy stored in the chemical bonds of a fuel Elastic: energy stored in a stretched or compressed object due to the position of the particles |
