Physics Flashcards
What is displacement?
the action of moving something from its place or position.
What was the displacement as he/she crosses the line?
0
What does the gradient tell you?
How fast or slow someone has gone judging by how steep the line is.
Josh crawls at 3cm/s how far in 20 seconds
3 x 20 =60
v=d x t
How do you calculate average speed?
Total distance= divided by time it took to get there.
What is the difference between distance and displacement?
Distance is a scalar quantity that refers to βhow much ground an object has coveredβ during its motion. Displacement is a vector quantity that refers to βhow far out of place an object isβ; it is the objectβs overall change in position.
What is the difference between speed and velocity?
velocity is the speed with a direction, while speed does not have a direction.
Definition acceleration?
a vehicleβs capacity to gain speed.
Distance definition?
the length of the space between two points
Speed definition?
the rate at which someone or something moves or operates or is able to move or operate.
Velocity definition?
the speed of something in a given direction.
