Topic 5 Distance displacement speed and velocity Flashcards
What is distance
How far an object has moved
What quantities distance
Scaler as it doesn’t involve direction
What Quantity is displacement
Vector quantity
What does displacement measure
The distance and direction in a straight line from an object starting point to the finish point
What is speed
Scaler
What is velocity
Vector
What does speed measure
How fast you’re going with no regard for direction
What does velocity measure
Speed in a given direction
Why can you have an object travelling at a constant speed with a change in velocity
Object is changing direction while staying at the same speed
What do objects moving in a circle At a constant speed have
Are constantly changing velocity of the direction is always changing so they are accelerating
Speed of a person walking
1.5 m/s
Speed of a person running
3 m/s
Speed of a person cycling
6 m/s
Speed of a car
25 m/s
Speed of a train
30 m/s
Speed of a plane
250 m/s
What affect the speed at which a person can walk run and cycle
The fitness , age , the distance travelled and the terrain
What does the speed of sound depend on
What are sound waves travel through and the speed of the wind
Speed of sound in air
330 m/s
What is windspeed affected by
Temperature
atmospheric pressures
and any large buildings or structures nearby
