In scale drawing, arrows should be drawn ............. to ..............
head to tail

What is the alternative to scalar drawing?
Pythagoras or trigonometry

When asked for the resultant, which two pieces of information should you give in your answer
The force/magnitude (length of the line) and direction (the angle)

A vector is resolved by which metod (finding x and y values)
Trigonometry  Cos and Sin mainly

An object is in equilibrium if
The forces acting in all directions are equal and so the resultant is 0

Displacement is
the straight line distance from any given point in a stated direction

Instantaneous speed is
the speed at a given instant of time

Average speed=
Average speed = Distance / Time

Velocity=
Velocity = Displacement / Time

Acceleration=
Acceleration = Change in Velocity / Time

On a velocitytime graph a horizontal line represents
Constant velocity, no acceleration

On a velocitytime graph a straight line slope shows
constant acceleration

On a displacementtime graph a horizontal line represents
Stationary object, no velocity

A displacementtime graph with a straight line slope shows
positive/negative constant velocity

How can you find displacement from a velocitytime graph?
Area under the curve
