Linear motion Flashcards
To learn the definition of linear motion. To know examples of linear motion, the graphs and equations
Describe linear motion?
Linear motion is a direct force applied to a body i.e when a force is directly applied to the center of a body’s mass
What is the definition of linear motion?
Linear motion is when a body moves in a straight line or constant curve where all parts move in the same direction, the same distance, in the same amount of time.
What are the 5 key descriptors of linear motion?
- distance
- speed
- displacement
- velocity
- acceleration/deceleration
What is the definition of distance?
The length of the path from start to finish
What is the definition of speed?
The rate of change in distance
What is the definition of displacement?
The shortest route from start to finish
What is the definition of velocity?
The rate of change in displacement
What is the definition of acceleration/deceleration?
The rate of change in velocity
What is a distance time graph?
A distance time graph shows the distance a body moves over a period of time. The curve gradient indicates the speed of the body at a particular instant
What is a speed/time graph?
A speed/time graph shows the speed of a body over a period of time. The curve gradient indicates the acceleration/deceleration of the body at a particular instant
What is a velocity/time graph?
A velocity/time graph shows the velocity of a body over a period of time. The curve gradient indicates the acceleration or deceleration of the body at a particular instant
The velocity/time graph also shows a change of direction of a body. How is this indicated?
A negative curve below the horizontal axis indicates a change in a body’s direction
What is a sporting example of linear motion?
A skeleton bob
