a) The acceleration of an object is determined by the resultant force acting on the object and the mass of the object: **a=f/m** or **f= m x a (f= m*a)**

b) The gradient of a distance–time graph represents speed.

c) Calculation of the speed of an object from the gradient of a distance–time graph.

d) The velocity of an object is its speed in a given direction.

e) The acceleration of an object is given by the equation: **a= v-u/ t** (where v is final velocity and u is initial velocity)

f) The gradient of a velocity–time graph represents acceleration

g) Calculation of the acceleration of an object from the gradient of a velocity–time graph

h) Calculation of the distance travelled by anobject from a velocity–time graph.
