The cards Question What is the speed of an object? Tap to flip Answer The distance it travels each second. Question What is the equation for speed? Tap to flip Answer Speed = distance ÷ time. Question What is the standard unit used to measure speed? Tap to flip Answer Metres per second (m/s). Question What is the unit miles per hour (mph) often used to measure? Tap to flip Answer The speeds of vehicles. Question For a certain distance, how does a greater speed affect the time taken? Tap to flip Answer The greater the speed, the shorter the time. Question In a certain time, how does a greater speed affect the distance travelled? Tap to flip Answer The greater the speed, the more distance travelled. Question What is average speed? Tap to flip Answer The overall distance travelled divided by the overall time for a journey. Question What does a larger gradient mean for a slope? Tap to flip Answer The slope is steeper. Question Does a trolley rolling down a ramp move at a constant speed? Tap to flip Answer No. It speeds up as it rolls down. Question What is instantaneous speed? Tap to flip Answer The speed of an object at a particular moment. Question What is a random error? Tap to flip Answer An error that varies from test to test in an uncontrolled way. Question How can the effect of random errors be reduced? Tap to flip Answer By taking repeat readings. Question Should anomalous readings be used when calculating an average? Tap to flip Answer No. Question Give one cause of timing errors in manual timing. Tap to flip Answer e.g. reaction times, or observing from an incorrect position. Question On a distance-time graph, what does the horizontal axis show? Tap to flip Answer Time. Question On a distance-time graph, what does the vertical axis show? Tap to flip Answer Distance. Question How do you work out the value of each small division on a graph scale? Tap to flip Answer Divide the value of a large division by the number of small divisions it contains. Question What does each point on a distance-time graph describe? Tap to flip Answer Where the object is at a point in time (not its speed). Question What does a level line on a distance-time graph show? Tap to flip Answer A stationary object (no movement). Question On a distance-time graph, what does a steeper line show? Tap to flip Answer Faster movement. Question On a distance-time graph, what do upward and downward sloping lines show? Tap to flip Answer Movement in opposite directions. Question What is the speed of a stationary object? Tap to flip Answer 0 m/s. Question Can a single distance value read from a distance-time graph give the speed? Tap to flip Answer No. Speed needs both a distance and a time. Question What is a resultant force? Tap to flip Answer The overall effect of a set of forces acting on an object. Question What is acceleration? Tap to flip Answer A change in speed or direction of movement. Question For how long does an object's speed change when a resultant force acts on it? Tap to flip Answer Throughout the time the resultant force is acting. Question By Newton's First Law, how does a moving object move if no resultant force acts on it? Tap to flip Answer It continues at a steady speed in a straight line. Question In which direction does friction act on a moving object? Tap to flip Answer Against the direction of movement. Question In which direction does the gravitational force on an object pull it? Tap to flip Answer Downwards, towards Earth. Question Why does a drag force act on an object moving through a fluid? Tap to flip Answer Because the object pushes particles of the fluid out of its way. Question What is the drag force on an object moving through air called? Tap to flip Answer Air resistance. Question What is the drag force on an object moving through water called? Tap to flip Answer Water resistance. Question What is a streamlined object? Tap to flip Answer An object shaped to reduce the drag forces acting on it. Question How does the drag force on an object moving through a fluid change as its speed increases? Tap to flip Answer It increases. Question How can streamlining affect the top speed of a vehicle? Tap to flip Answer It can increase it. Question What does a parachute do to the drag force? Tap to flip Answer It increases the drag force, slowing down the object it is attached to. Question How does the size of a parachute's surface affect its drag? Tap to flip Answer The larger the surface, the bigger the drag. Question At top speed, how does the drag on a parachute compare with the force of gravity on the jumper? Tap to flip Answer They are the same size. Question Where do all objects fall at the same rate? Tap to flip Answer Only in a vacuum. Question When does a falling object reach terminal velocity? Tap to flip Answer When the drag force and the gravitational force on it are equal. Question What two things does the drag force on a falling object depend on? Tap to flip Answer Its speed and its shape. Question How can the terminal velocity of a falling object be changed? Tap to flip Answer By changing the drag force, e.g. with a parachute. Question How does the gravitational force on a falling object change as it falls? Tap to flip Answer It stays constant.

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.
