What does an object in uniform motion travel equal to?
Displacements in equal time intervals.
How is uniform motion represented on a position-time graph?
As a straight line.
What does magnitude refer to?
The size of a measurement or the amount you are counting.
What is time?
A concept that describes when an event occurs.
What is initial time?
When the event began.
What is final time?
When the event finished.
What is time interval?
The difference between the final and initial times.
How is time interval calculated?
Delta F= Time (f) - Time (i)
Define distance.
A scalar quantity that describes the length of a path between two points or locations.
Define position.
A vector quantity that describes a specific point relative to a reference point.
What is the SI unit for both distance and position?
Metres (m)
Define displacement.
The straight-line distance and direction from one point to another. It describes how much an object’s position has changed.
How do you calculate displacement?
Final Position - Initial Position
What is the SI unit for displacement?
Metres (m)
