The cards Question How is average speed calculated? Tap to flip Answer Average speed = distance ÷ time. Question What is instantaneous speed? Tap to flip Answer The speed of an object at a particular moment. Question What is a scalar quantity? Tap to flip Answer A quantity that has magnitude (size) only, with no direction. Question Are speed and distance scalar or vector quantities? Tap to flip Answer Scalar quantities. Question What is relative speed? Tap to flip Answer The difference in the speeds of objects, taking their directions of movement into account. Question How does a dynamics trolley's speed change as it rolls down a steep ramp? Tap to flip Answer It keeps speeding up (accelerating) along the whole length of the ramp. Question How is instantaneous speed related to average speed? Tap to flip Answer Instantaneous speed is the average speed over a very short time period. Question What is an anomalous reading? Tap to flip Answer A result that lies significantly outside the expected pattern in a set of results. Question What should be done with an anomalous reading in a set of repeat readings? Tap to flip Answer Repeat it, then replace it or remove it from the set. Question When is a measurement repeatable? Tap to flip Answer When the same person repeats the investigation with the same method and gets the same or similar results. Question When is a measurement reproducible? Tap to flip Answer When similar results come from the same person using a different method, or a different person using the same method. Question What does it mean if two variables are directly proportional? Tap to flip Answer When one increases, the other increases at the same rate. Question Why are repeated readings taken by different observers? Tap to flip Answer To check for systematic errors. Question What is velocity? Tap to flip Answer The speed of an object in a particular direction. Question What is displacement? Tap to flip Answer The distance travelled in a particular direction from a starting point. Question What is a vector quantity? Tap to flip Answer A quantity with both magnitude (size) and direction. Question How does the sign of a velocity show its direction? Tap to flip Answer Velocity is positive in one direction and negative in the opposite direction. Question What does the gradient of a displacement-time graph give? Tap to flip Answer The velocity of the object. Question What does a downward-sloping (negative) gradient on a displacement-time graph show? Tap to flip Answer Velocity in the opposite direction. Question What does a negative value of displacement represent? Tap to flip Answer A position 'behind' the starting position. Question What does a motion sensor measure? Tap to flip Answer The distance between itself and an object. Question When does dividing one pair of coordinates on a displacement-time graph give the velocity at that point? Tap to flip Answer Only for a straight-line graph that passes through the origin. Question What is acceleration? Tap to flip Answer The rate of change of velocity: how much the velocity changes each second. Question What is the equation for average acceleration? Tap to flip Answer Average acceleration = change of velocity ÷ time (a = Δv/t). Question What does the symbol Δv represent? Tap to flip Answer The change in velocity. Question What is the sign of the acceleration of a decelerating object? Tap to flip Answer Negative. Question Can an object be accelerating while moving at a constant speed? Tap to flip Answer Yes, if its direction changes, as in circular motion. Question How is change in velocity calculated? Tap to flip Answer Change in velocity = final velocity − initial velocity. Question Why can final velocity alone not be used to compare accelerations? Tap to flip Answer The time over which the object accelerates must also be taken into account. Question How does a light gate measure velocity? Tap to flip Answer An infrared beam turns a timer on and off as an object passes through it. Question What is a compensated ramp? Tap to flip Answer A ramp sloped to counteract the effect of friction. Question What is uniform acceleration? Tap to flip Answer Acceleration that is constant. Question What does the gradient of a velocity-time graph give? Tap to flip Answer The acceleration. Question What does a falling line on a velocity-time graph show? Tap to flip Answer Decreasing velocity (deceleration), which is a negative acceleration. Question In the acceleration equation a = Δv/t, what does t stand for? Tap to flip Answer A change of time, not a single moment in time. Question Do a displacement-time graph and a velocity-time graph of the same motion have the same shape? Tap to flip Answer No, they have different shapes. Question How can average velocity be found from initial and final velocity? Tap to flip Answer Average velocity = (initial velocity + final velocity) ÷ 2. Question Which equation results from combining the equations for average acceleration and average velocity? Tap to flip Answer v² − u² = 2as Question What is initial velocity? Tap to flip Answer The velocity an object starts with during a phase of motion.

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.
