IGCSE 1b: Movement and Position

Define speed

• Distance travelled per unit time
• Time travelled per unit distance

What is the relationship between speed, distance, and time?

• speed=distance/time
• speed = distance x time
• speed = time / distance

What is the relationship between average speed, total distance, and total time?

• average speed = total distance / total time
• average speed = total distance x time
• average speed = total time / total distance

What is the relationship between v, d, and t?

• v=d/t
• v=dt
• v=t/d

What feature of a distance time graph shows speed?

• Gradient
• Area under graph
• y-intercept
• x-intercept

What feature of a distance time graph shows a stationary object?

• Gradient of zero/horizontal line
• Upward curving line
• Constant positive gradient
• Constant negative gradient

Define acceleration

• Rate of change of velocity
• Rate of change of distance
• Rate of change of speed

What is the relationship between acceleration, final velocity, initial velocity, and time?

• acceleration=(final velocity - initial velocity)/time
• acceleration = (final velocity + initial velocity) / time
• acceleration = (initial velocity - final velocity) / time
• acceleration = time / (final velocity - initial velocity)
• acceleration = time / (final velocity + initial velocity)

What is the relationship between a, v, u, and t?

• a=(v-u)/t
• a=(v+u)/t
• a=(u-v)/t
• a=t/(v-u)
• a=t/(v+u)

What feature of a velocity time graph shows acceleration?

• Gradient
• Area under graph
• y-intercept
• x-intercept
