km / s
A car travels 100 km. The journey takes two hours. The highest speed of the car is 80 km/h and the lowest speed is 40 km/h.
What is the average speed for the journey?
40 km/h
50 km/h
60 km/h
120 km/h
What is the correct equation used to calculate the acceleration of an object?
a = d / t2
a = t / (v - u)
a = (v - u) / t
a = (v - u) . t

What is stated by the Law of Conservation of Energy?
Energy cannot be created or destroyed, but it can change from one form to another.
The energy of a system will increase over tiime.
The energy of a system will decrease over time.
Energy is only conserved in the absence of friction.
