Define displacement
Displacement is the distance moved in a particular direction
Displacement is a vector quantity, which means it has both magnitude and direction.
Define speed
Speed is the distance moved per second
Speed is a scalar quantity, meaning it only has magnitude.
Define velocity
Velocity is the displacement per second
Velocity is a vector quantity, indicating both speed and direction.
Define acceleration
Acceleration is the rate of change of velocity
Acceleration can be positive (speeding up) or negative (slowing down).
How can you calculate speed from a distance-time graph?
Speed = gradient of distance-time graph
The gradient represents how much distance is covered over time.
How can you calculate velocity from a displacement-time graph?
Velocity = gradient of displacement-time graph
The gradient indicates the rate of change of displacement over time.
How can you calculate the rate of change of speed from a speed-time graph?
Rate of change of speed = gradient of speed-time graph
This gradient shows how speed changes over time.
How can you calculate acceleration from a velocity-time graph?
Acceleration = gradient of velocity-time graph
The gradient indicates how velocity changes over time.
How can you calculate distance travelled from a speed-time graph?
Distance = area under speed-time graph
The area represents the total distance covered during the time interval.
How can you calculate displacement from a velocity-time graph?
Displacement = area under velocity-time graph
The area under the graph represents the total displacement over the time period.
