Acceleration

BC Science Probe 10Chapter 13

Acceleration

• Acceleration is the rate of change of velocity. It is a vector quantity.

=

Acceleration

• The units used for acceleration are m/s2

• This actually means meters per second per second.

• Let’s have a look a sample problem 1 on page 374.

Acceleration

• On a velocity time graph, the slope of the line = the acceleration.

Acceleration

• Negative acceleration is when the final velocity() is less than the initial velocity ().

• We will try sample problem 2 on page 377.

Acceleration

• Now try the CYU questions on page 379.– #2,4,5,6

Graphing Accelerated Motion

• Constant acceleration shows a straight line on a velocity-time graph.

Graphing Accelerated Motion

• The area under a velocity-time graph shows the displacement.

Graphing Accelerated Motion

• Sample problems 1 and 2 on page 382 can help us practice this.
