Gravity is a force that pulls a certain thing towards the centre of the earth. 2 of 18 Orbits? Planets and satellites are kept orbiting by gravitational pull, for planets to the the sun , for satellites to the earth. 3 of 18 The moment of a force is given by the equation? Moment=force(N)* distance from pivot 4 of 18 instantaneous speed is what? the speed of an object at a particular moment in time.- measured in metres per second. 5 of 18 Electrical Energy? is very useful, because it is easily converted into other forms. wherever there is a current flowing there is electrical energy. 6 of 18 Light energy? anything luminous gives off light energy. Things like the sun, light bulbs and candles. 7 of 18 Sound energy? Anything noisy gives off sound energy. 8 of 18 Kinetic Energy? Anything that moves gives off kinetic energy. 9 of 18 Thermal Energy? Anything with a temperature above absolute Zero (-273℃) has heat energy. 10 of 18 Gravitational potential energy? Anything that is above the ground has gravitational potential energy. 11 of 18 Elastic Energy? Anything stretched has elastic energy. 12 of 18 Chemical Energy? Anything with stored energy which can be released by a chemical reaction has chemical energy. 13 of 18 Heat and temperature are different? Temperature is a measure of how hot something is , it is measured in ℃. Heat is a form of energy , and it's measured in joules. 14 of 18 pressure is measured in what? pascals. 15 of 18 pressure= force divided by area 16 of 18 speed? how far you have travelled in a certain time. 17 of 18 SIDOT? Speed is distance over time. 18 of 18
