Ch1 Movement And Position Flashcards
What is the difference between speed and velocity
They both have the same equation, but velocity has a direction
What is equation for acceleration
Change in velocity /time
In a velocity time graph, what does a shallow gradient mean?
Low acceleration
In a velocity time graph, what does a steep gradient mean?
High acceleration
In a velocity time graph what does no gradient mean
No acceleration
In a velocity time graph, what does a negative gradient mean?
Deceleration
Is force scalar or vector
Vector
What is the equation for speed
Speed = distance/time
What does the slope or gradient in a distance time graph show us
The speed of the car
What does a straight line in a distance time graph show us?
That the car is travelling at a constant speed
What does a steep gradient in a distance time graph show us
The car is travelling at a fast speed
