The cards Question What is a force? Tap to flip Answer A push or a pull. Question What is a force needed to change about an object? Tap to flip Answer Its motion or its shape. Question Which is harder to stop: a faster moving object or a slower one? Tap to flip Answer The faster one. Question Which is harder to stop: a heavier moving object or a lighter one? Tap to flip Answer The heavier one. Question Does an object with greater mass need a greater or a smaller force to start it moving, stop it or change its direction? Tap to flip Answer A greater force. Question Where do the forces acting on an object come from? Tap to flip Answer From other objects. Question When does a moving object slow down? Tap to flip Answer When forces act on it opposite to its direction of motion. Question What is a contact force? Tap to flip Answer A force that acts only when the objects are touching. Question What is a non-contact force? Tap to flip Answer A force that can act whether or not the objects are touching. Question What is friction? Tap to flip Answer The force of one surface gripping or rubbing on another. Question What is drag? Tap to flip Answer A contact force that pushes against objects moving through liquids or gases. Question How should a force be described as an interaction between two objects? Tap to flip Answer As 'the force of object A on object B'. Question What unit is the size of a force measured in? Tap to flip Answer The newton (N). Question What instrument measures the size of a force? Tap to flip Answer A newton meter. Question What is a zero error? Tap to flip Answer When a measuring device should read zero but does not. Question On a force diagram, what does the length of a force arrow show? Tap to flip Answer The size (strength) of the force. Question Which way must a force arrow point? Tap to flip Answer In the same direction as the force it represents. Question Where is a force arrow drawn starting from? Tap to flip Answer From the point where the force acts. Question What are balanced forces? Tap to flip Answer Two forces of equal size acting in opposite directions on an object, which cancel each other out. Question What is the resultant force on an object? Tap to flip Answer The sum of the forces acting on it, taking their directions into account: the 'force left over'. Question When the forces on an object are balanced, what happens to its speed? Tap to flip Answer It does not change, because there is no resultant force. Question Two forces act on an object in opposite directions. Which way does the resultant force act? Tap to flip Answer In the direction of the bigger force. Question For a given object, what does a greater resultant force cause? Tap to flip Answer A greater or faster change in speed. Question What does the direction of the resultant force show: the direction of motion or the direction of the change? Tap to flip Answer The direction of the change, not the direction of motion. Question What does friction do to movement between surfaces? Tap to flip Answer It prevents or slows it down. Question What causes friction? Tap to flip Answer The roughness of the surfaces. Question What is a lubricant? Tap to flip Answer A substance added between two surfaces to reduce the friction between them. Question In a fair test, which variable is changed? Tap to flip Answer Only the variable being tested. Question What is an anomalous result? Tap to flip Answer A result that does not fit the pattern seen in the other measurements. Question What does a mean do with repeat measurements? Tap to flip Answer It combines them into a single result. Question What is a categoric variable? Tap to flip Answer A variable that comes in distinct, separate categories. Question What is a continuous variable? Tap to flip Answer A variable that can take any value on a numerical scale, including decimals. Question Which kind of graph is used when the variable you changed is categoric? Tap to flip Answer A bar chart. Question What does a conclusion do? Tap to flip Answer It states what you found out in an experiment and explains how you know. Question Which energy store does a moving object have? Tap to flip Answer A kinetic store. Question Which energy store does a raised object have? Tap to flip Answer A gravitational store. Question Which energy store does a stretched or squashed object have? Tap to flip Answer An elastic store. Question Why does an object have a thermal store of energy? Tap to flip Answer Because of its temperature. Question Which objects have a chemical store of energy? Tap to flip Answer Objects that contain chemicals that can react. Question Is energy a physical substance that objects have? Tap to flip Answer No. It is a label for having properties that let objects interact, cause changes and make things happen. Question Can energy be created or destroyed? Tap to flip Answer No. Question What happens to energy stores during an energy transfer? Tap to flip Answer The energy in some stores decreases and the energy in others increases.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong. Flash Feed is not affiliated with any source named here.
