Step 2: Determine Time Intervals. Calculate the time intervals (Δt) by subtracting t1 from t2. This value represents the elapsed time during which the object was in motion. Step 3: Calculate Average ...

Velocity-time graphs show how the velocity ... Average speed = total distance ÷ total time = 1,700 m ÷ 50 s = 34 m/s. Look at this velocity-time graph and answer the question.

If the velocity-time graph is curved, the acceleration can be found by calculating the gradient of a tangent to the curve. Example The velocity of a sledge as it slides down a hill is shown in the ...
