1 Motion for Constant Acceleration

2 Equations of Motion for Constant Acceleration In this lesson the students are shown how to use a velocity-time graph to develop the equations of motion for constant acceleration. To give the students confidence, they are sometimes asked to share ideas with a partner.

3 We can use a velocity-time graph to find some equations that hold for a body moving in a straight line with constant acceleration. velocity (ms -1 ) time (s ) u v t0 Suppose when the time is 0... At any time, t, we let the velocity be v. the velocity is u. Ans: The gradient gives the acceleration. Remind your partner how to find acceleration from a velocity-time graph. Constant acceleration means the graph is a straight line.

4 We can use a velocity-time graph to find some equations that hold for a body moving in a straight line with constant acceleration. velocity (ms -1 ) time (s ) u v t a v u t So, v u 0 Suppose when the time is 0... the velocity is u. t From this equation we can find the value of any of the 4 quantities if we know the other 3. At any time, t, we let the velocity be v. Constant acceleration means the graph is a straight line.

5 a v u t a t v u v u a t Multiplying by t : u a t v We usually learn the formula with v as the subject. The velocity, u, at the start of the time is often called the initial velocity.
