P9 - Motion Flashcards
1
Q
What kind of quantity is speed?
A
It is a scalar quantity
2
Q
What is the formula to calculate speed?
A
Speed/v (m/s)= distance/s (m)/ time/t (s)
3
Q
What would stationary look like on a distance time graph ?
A
The line would be staright
4
Q
What is the formula for acceleration?
A
acceleration (m/s^2) = final velocity - initial velocity(m/s) / time taken for the change(s)
5
Q
How do you calculate the gradient of a line?
A
Delta y / Delta x
6
Q
What is acceleration?
A
The rate of change of velocity.
7
Q
How do you calculate the speed on graph if the line is constantly changing?
A
You draw a tangent.
8
Q
How is acceleration represented on a velocity - time graph?
A
The acceleration of an object is represented by gradient of the line on a velocity-time graph.
