## Learning outcomes (By the end of this unit you should be able to...)

- Know the meaning of the terms speed and acceleration.

- Calculate the speed of an object knowing how far it’s travelled in a given time.

- Recognise that the slope of a distance time graph is speed. and speed time is acceleration.

- Appreciate the existence of errors in measurements.

- Understand how errors in measurement can be reduced by taking the average of a number of readings.

- Show how motion can be represented by graphs.

- Understand the effects of balanced and unbalanced forces.

- Understand that the velocity of an object will only change if it is acted upon by an unbalanced force.
