Acceleration and motion
Acceleration and motion

  • Acceleration is the change in velocity divided by the time it takes for the change to occur.

  • When you watch a plane moving for the first few seconds it seems to barley move, however with each passing second you can see it moving faster and faster , this is an example of acceleration.


  • Like velocity, acceleration has a direction. If an object speeds up, the acceleration is in the direction that the object is moving.

  • If an object slows down, the acceleration is opposite to the direction that the object is moving.

Types of accelerating
Types of accelerating

  • There are three types of acceleration ,speeding up, slowing down, and changing direction .

  • Speeding up is like when you get on a bike and begin to pedal. The bike moves slowly at first, and then accelerates because its speed increases.

  • Slowing down is like when you are riding a bike at a quick speed, and you apply the brakes. This causes you to slow down.

  • Changing direction in acceleration is that the motion ,is not always along a straight line.

Calculating acceleration
Calculating Acceleration

  • If an object is moving in a straight line, its acceleration can be calculated using this equation.

Positive and negative acceleration
Positive and Negative Acceleration

  • Positive acceleration is when the object is speeding up, but negative acceleration ,is when the object is slowing down.

  • When you speed up, your final speed always will be greater than your initial speed. So subtracting your initial speed from your final speed gives a positive number.

  • Because your final speed is less than your initial speed, your acceleration is negative when you slow down.

Graphing acceleration
Graphing acceleration

  • A speed-time graph can be used to find acceleration. When the line rises, the object is speeding up.

  • When the line falls, the object is slowing down.
