Motion- velocity, acceleraion, displacement and time Flashcards
Define velocity
The rate of change of displacement
How do you calculate velocity?
v= change in displacement/time taken
Define Acceleration
The rate of change of velocity
How do you calculate acceleration?
a=change in velocity/time taken
What does constant acceleration look like on a displacement time graph?
An increasing curve starting from the origin
What does constant acceleration look like on a velocity time graph?
Straight line starting from the origin
What does constant acceleration look like on a acceleration time graph?
A straight line that goes horizontally from the y-axes
How do you calculate the displacement on a velocity time graph?
Calculate the area under the graph
How would you calculate velocity on an acceleration time graph?
The area under the graph
What is the gradient on a velocity time graph?
acceleration
On a velocity time graph what does a curved graph show?
non-uniform acceleration
What does a change in sign of velocity indicate?
A change in direction
