Speed
The SI unit for speed.
What is m/s?
The negative slope of a speed-time graph.
What is deceleration (negative acceleration/ slowing down)?
The energy of motion
What is kinetic energy
A positive acceleration tells you this
What is speeding up
An object with a mass of 3 kg is raised off the ground 5 m. Calculate potential energy
What is 150 J
This results in a change in position.
What is motion?
What is constant velocity
Energy that is stored in an object as it is raised off the ground
What is potential energy
A negative acceleration tells this.
What is slowing down/deceleration?
Calculate the speed of a dog running through a field if he covers 25 m in 10 s.
What is 2.5 m/s?
The expression/equation/formula for speed.

What is 100 km/h northwest?
The difference between speed and velocity.
What is direction?
A slope of zero on a distance-time graph.
What is object at rest?
The SI unit of energy
What is joule
The expression/formula for acceleration.
What is final velocity-initial velocity/time?
