The steeper the line, the faster the object is moving . If the forces acting on an object are not equal, then the object will slow down or speed up. If the thrust and drag are equal, then the car is travelling at a constant speed. We call it a vector . Acceleration Acceleration is a change in the velocity of the object.
Acceleration is also a vector.
This shows the velocity of the object. Also the area under a velocity-time graph shows the distance travelled. Question 1 Question 2 Question 3 Question 4 Look at the graph below. A go-cart is released from the top of a hill. It accelerates down the hill.
