Slide 3 - Slide

§4.3 - Learning Goals:
  • I can describe the concept of acceleration and understand which measurements and units are necessary to calculate it.
  • I can calculate the acceleration of an object using the acceleration formula.
  • I can create and interpret v,t-diagrams relating to an object’s change in motion.
  • I can use an object’s resultant force to determine what type of motion it has.


P.172-175

What is acceleration?
Acceleration is change in speed, so speeding up or slowing down, measured in meters per second squared (m/s2). 
It is calculated by:
P.172-175

Slide 6 - Slide

What is acceleration?
P.172-175

Slide 7 - Slide

What is deceleration?
Deceleration occurs when an object’s speed decreases, in other words, a negative acceleration.

P.172-175

Slide 8 - Slide

Uniform motion
Uniform motion - When the speed stays constant

P.172-175

Slide 9 - Slide

Acceleration
Acceleration: speed increases→ Graph gets steeper


P.172-175

Slide 10 - Slide

Deceleration
Deceleration: speed decreases → Graph gets flatter



P.172-175

Let's practice:
P.172-175
A car is accelerating for 8 seconds, increasing by 20 m/s every second. Complete the following table, then make an v,t diagram of your results.
