Distance, Speed and Acceleration

Name the 4 terms which can describe the motion of a body?

1. Stationary

2. Constant speed or velocity

3. Accelerating

4. Decelerating

How do you calculate speed or velocity?

Speed = distance (m) / time (s)

What is velocity mean?

Velocity is the speed in a specific direction

How do you calculate acceleration or deceleration?

Acceleration = change in velocity / time

How can acceleration or deceleration be calculated using a graph?

You can calculate the gradient of the line

How can the distance travelled be calculated?

By calculating the area under the line of the graph

Name 3 things that affect thinking distance?

1. Speed

2. Alcohol or drugs

3. Tiredness

Name 3 things that affect braking distance?

1. Speed

2. Road conditions (e.g. rain)

3. Condition of the brakes
