P2.1 Motion Flashcards
What is Motion?
The process of moving or being moved
What is velocity?
Velocity is speed with a direction.
What is the speed, distance, time equation?
Distance = speed x time
What does gradient tell you on a distance time graph?
Gradient gives you acceleration
What does a horizontal line mean on a Velocity/Time graph?
That it is travelling at a constant speed.
What does a horizontal line mean on a Distance/Time graph?
It is stationary.
The 1)……… the slope the 2)……….. the acceleration.
1) steeper
2) greater
What is the formula for acceleration?
(final velocity - initial velocity) / time
What do curves represent on a distance-time graph?
Acceleration or deceleration
How do you calculate the gradient of the line on a distance-time graph?
change in vertical axis divided by change in horizontal axis
What represents the distance covered on a velocity- time graph?
The area under the line
how to calculate momentum?
momentum=mass x velocity (p=mv)
