How do you calculate acceleration?

Subtract the starting velocity from the final velocity and divide by the time, giving m/s². A negative value means the object is slowing down. Calculate Acceleration From Velocity Changes also rearranges the formula to find final velocity and time.

What does the slope of a distance and time graph show?

The slope shows the speed. A steeper line means a faster speed, and a straight line means a steady speed. The cycling race sheet asks students to explain this from their own graph.

Speed is how far an object travels in a unit of time, and acceleration is how fast its velocity changes. There are 2 sheets for 8th grade here, each with an answer key. Position and Speed Graphs of a Cycling Race finds average speeds for five 300 m segments and graphs them, and Calculate Acceleration From Velocity Changes uses a = (final velocity minus starting velocity) / time for trips such as a train leaving a station.

Frequently Asked Questions

Divide the distance by the time. A 300 m segment ridden in 25.0 s has an average speed of 12.0 m/s. Position and Speed Graphs of a Cycling Race repeats this for five segments and the whole race.
