Science: Speed, Velocity and Acceleration

Average Speed: distance travelled per unit of time (m/s) Velocity: displacement per unit of time (m/s) Average Speed is SCALAR, while velocity is a VECTOR Distance-Speed-Time Triangles Usage: Average Speed \(=\) Distance \(\div\) Time Distance \(=\) Average Speed \(\times\) Time Time \(=\) Distance \(\div\) Average Speed Acceleration Acceleration is the rate at which an object’s velocity CHANGES Acceleration is measured in \(m/s^2\) (metres per second squared) Acceleration can be found by dividing the applied force by the mass of the object \(a = F/m\) Acceleration is a VECTOR quantity.

Science: Distance and Displacement

Distance: the measurement of the length between two points Displacement: the CHANGE in an object’s position (straight line between start and end points) NOTE: An object can travel a large distance and still have zero displacement Distance is SCALAR (e.
