Car is accelerating. Draw on labelled arrows for all forward and back forces. Draw on an arrow to represent the resultant force

Which vehicle has the fastest acceleration? Why? The motorbike has the fastest acceleration. Even though it has less thrust from the engine, its mass is much smaller than the cars. Large forward force = fast acceleration Small mass = fast acceleration

Formula One cars can accelerate very quickly. What features enable them to do this? Streamlined to give less air resistance so resultant forward force is high Tyres have no tread (slicks) meaning less friction Large thrust (forward force) from powerful engine Mass kept as low as possible (made out of carbon fibre)

How fast an object accelerates depends on: Its mass (high mass = low acceleration) Its resultant forward force (high force = high acceleration) Acceleration = Force / Mass Force = Mass x Acceleration F M A Practice using this by doing questions 1 and 2 on page 198 of skier book.
