Average speed
The total distance traveled divided by the time taken.
Gradient
The slope of a distance-time graph, which represents the speed of an object.
Distance-time graphs
Graphs that show the relationship between distance and time. A straight line indicates a steady speed, while a curved line indicates changing speed.
Velocity-time graphs
Graphs that show the relationship between velocity and time. A horizontal straight line indicates a steady speed, while a curved line indicates changing speed.
Velocity
The rate of change of displacement over time, a vector quantity.
Displacement
The change in position of an object.
Distance
The total distance traveled by an object, calculated by multiplying speed by time.
Acceleration
The rate of change of velocity over time, calculated as (final velocity - initial velocity) divided by time.
SUVAT equations
Equations used to solve problems involving motion. Examples include s = (v + u) / 2 x t, v² = u² + 2as, where s is displacement, v is final velocity, u is initial velocity, a is acceleration, and t is time.
