What is speed? how fast something is going How do you work out the speed? speed= distance ÷ time What is velocity speed with direction What do distance-time graphs show? how something is travelling over a period of time What is the gradient of a distance-time graph equal to? speed- how fast the object is travelling What does the downwards gradient on a distance-time graph show? it means its going back towards its starting location What do the flat...

PHYSICAL SCIENCE EXAM QUESTIONS WITH COMPLETE SOLUTIONS VERIFIED ALREADY PASSED What two factors determine how much gravitational potential energy an object has? Select one: a. shape and speed of the object b. shape of the object and its position relative to the ground c. weight and speed of the object d. weight of the object and height above the ground d. weight of the object and height above the ground The gravitational potential energy of an object changes when which of the followin...

Energy is transferred between stores -:- Thermal, kinetic, gravitational potential, elastic potential, chemical, magnetic, electrostatic, nuclear Energy is transferred... -:- Mechanically (by a force doing work), electrically (work done by moving charges), by heating or by radiation (like light or sound) When a system changes, energy is transferred -:- It can be transferred into or away from the system, between objects in the system or between different types of energy stores.
