Test Jan/Feb science Flashcards
What is a vector
It is both Direction And size an exzample of this is mass and distance
What is a scalar quantity
A quantity that has magnitude but not Direction
What is velocity
Slowing down to go round a Conner /changing speed
What is de-acceleration
Slowing down
What is acceleration
Going faster
What is displacement
Traveling in a straight line
What is displacement
Training in a Straight line
What is that equation for speed
Distance divided by time
What is the equation for distance
Speed * time
What is that equation for time
Distance divided by speed
In velocity time graph a horizontal line means
Travelling constant speed
As the line gets Steep on a velocity time graph what does this mean
It is getting a greater acceleration
What is the equation for acceleration
change in velocity divided by time take
What is that equation for time
Change in velocity divided by acceleration
What is the equation for a change in velocity
Time times acceleration
How fast does gravity move
10m/s
In a 6 mark question describing a velocity time graph what 6 points can u use
The overall distance the overall time A line going up means going faster A line going down means going slower When there moving at there fastest a Horrzontle line means staying at the same speed
What does the horizontal line on a distance time graph mean
Stopping/having a break
What does the line going up what’s mean on a distance time graph
Going further
