Motion Flashcards
What is the correct equation for calculating speed?
The correct equation is distance divided by time
What are the correct units for speed?
Metres per second are the correct units
What is the correct equation for calculating time?
The correct equation is distance divided by time.
What is the correct equation for calculating distance?
The correct equation is speed multiplied by time.
What does a horizontal line in a distance-time graph show?
A horizontal line in a distance-time graph shows a stationary object.
What does a steep line in a distance-time graph show?
A steep line in a distance-time graph shows a fast moving object
What does a gently sloping line in a distance-time graph show?
A gently sloping line in a distance-time graph shows a slow moving object.
What goes on the x-axis in a distance-time graph?
Time goes on the x-axis in a distance-time graph. Distance goes on the y-axis.
How do you calculate the relative speed of objects moving in the same direction?
To calculate the relative speed of objects moving in the same direction, we subtract the slowest speed from the fastest speed.
How do you calculate the relative speed of objects moving in the opposite direction?
To calculate the relative speed of objects moving in opposite directions, we add both speeds together.
