Acceleration Video
Slide2SWBAT explain how changes in velocity and time affect the acceleration of an object
Slide3Acceleration is a measure of
the change in velocity per unit of time
When the velocity of an object is changing, it is
accelerating
Negative acceleration: slowing downPositive acceleration: speeding up
What is acceleration?
Slide4Car A and Car B both accelerate from 0 mph to 60 mph. If it takes Car A 30 seconds to do this and Car B 45 seconds to do this, which car has a greater acceleration?
Check For Understanding
Slide5Car A and Car B both accelerate from rest during a 10 second time period. If Car A is moving 50 mph at the end of the time interval and Car B is moving 45 mph, which car has a greater acceleration?
Check For Understanding
Slide6What is the unit of acceleration?
Velocity / time
Distance / time
Time / velocity
Time / distance
Check For Understanding
Slide7Velocity can change in two ways:
The speed can increase or decrease
The direction can change
How Can Velocity Change?
Slide8Is it possible for an object to accelerate if it doesn’t change speed?
Check For Understanding
Slide9Recall: Draw a motion diagram for an object with positive acceleration, negative acceleration, and zero acceleration.
Understand: Differentiate between positive, negative, and zero acceleration in terms of velocity.
Apply: List 5 real world examples of acceleration.
Analyze: Differentiate between velocity
and acceleration,
providing examples of each.
Synthesize:
Develop an experiment to test whether a Ferrari or a Lamborghini can accelerate faster.
Evaluate: Jake tells his friend that acceleration can only occur if there is a change in speed. Evaluate Jake’s statement and provide a concrete example to support your claim.
