Unit 1 - Motion Flashcards
What is a vector?
A quantity with magnitude & direction
How are vectors added?
Tip to tail
What is distance?
The sum of the distances of each stage of the journey
What is displacement?
The shortest route between the start and finish point measured in a straight line
What is speed?
The distance travelled per second
What is velocity?
The displacement travelled per second
Horizontal vector component formula?
V = V cos(x)
Vertical vector component formula?
V = v sin(x)
What can the equations of motion be applied to?
Any object moving with constant acceleration in a straight line
Decreasing velocity is represented by?
A negative sign
How is velocity determined from a displacement - time graph?
The gradient
Gradient = displacement/time = velocity
What is the area under a velocity time graph equal to?
Displacement
What is a scalar?
A scalar is a quantity with just a magnitude
