SP1a - What is a scalar quantity?

A quantity with a magnitude (size) but no direction

2

SP1a - What is a vecotr quantity?

A quantity with a magnitude (size) and direction.

3

SP1a - What are the six main vector quantities?

  • Velocity
  • Displacement
  • Acceleration
  • Force
  • Weight
  • Momentum

4

SP1b - How do you work out average speed?

Speed (m/s) = Distance(m) / Time(s)

5

SP1b - What is the average speed of walking and cycling?

  • Walking: 1.4m/s
  • Cycling: 6m/s

6

SP1b - What are the two things you can use to measure speed in an experiment?

  • Stopwatch

7

SP1b - On a distance/time graph, what does the gradient represent?

The velocity

8

SP1b - On a distance/time graph, what does a horizontal line represent?

The object is stationary

9

SP1b - On a distance/time graph, what does a curve represent?

The object is accelerating/deccelerating

10

SP1c - How do you calculate acceleration?

Acceleration (m/s²)

=

Change in velocity (m/s) ÷ Time (s)

11

SP1c - What is the value of acceleration due to gravity?

9.8m/s² (rounded to 10m/s²)

12

SP1d - What does a straight slope mean on a velocity time graph?

Acceleration

13

SP1d - What does a horizontal line mean on a velocity time graph?

The object is moving at a constant velocity

14

SP1d - What does a curve mean on a velocity time graph?

Changing acceleration

15

SP1d - What does the area under a velocity time graph represent?

The distance covered
