The movement of objects can be described using motion graphs and numerical values. These are both used to help in the design of faster and more efficient vehicles.
What is a typical walking speed?
What quantity is the rate of change of velocity?
How is speed found from a distance-time graph?
It is read from the vertical (y) axis
It is the gradient of line
It is the area under the line
How is velocity found from a velocity-time graph?
How is acceleration found from a velocity-time graph?
What is the unit of acceleration?
Metres per second squared (m/s²)
Metres per second (m/s)
What is the acceleration of a horse that accelerates from rest to 4 m/s in 8 seconds?
What is the average speed of a runner that travels 200 m in 40 seconds?
How is displacement found from a velocity-time graph? - Higher
What happens to the speed and velocity of a planet in a circular orbit around a star?
The velocity changes and the speed changes
The velocity changes but the speed remains constant
The speed changes but the velocity remains constant
