acceleration v time

​Acceleration v Time

By Alex Davila

​SWBAT: interpret acceleration graphs, find velocity under the curve

​Acceleration is the change of speed or direction.
If a car accelerates at the beginning and then stops accelerating, this does not mean the car stops moving, it continues moving at the velocity it stopeed accelerating in.

​

Interpreting Acceleration

Multiple Choice

For how long did the object accelerate?

• 3s

• 2s

• 5s

• 4s

Multiple Choice

After accelerating for 3 seconds what happened to the car?

• It stopped moving

• Remained in constant velocity

• Slowed down

• Changed speed

​When a ball or anything on earth falls it gets faster as it falls. The reason is because gravity force is causing an acceleration making the object fall 10m/s2

You can figure out the end velocity before hitting the ground by getting the area under the curve

​

Acceleration free fall

​To find velocity in this graph we must find the area under the curve A=BxH

Once we find it we know what was the velocity when it stopped accelerating.

​

Finding Velocity

Multiple Choice

A ball is falling for 10s. What was the final velocity at 10s before hitting the ground?

• -100m/s

• 10m/s

• 100m/s

• 0m/s

Multiple Choice

What is the velocity of this car after 5s?

• 10m/s

• 15m/s

• 39m/s

• 15m/s²

Multiple Choice

A soccer ball falls from the building, what will the acceleration be?

• -9.8m/s²

• 9.8m/s²

• 10m/s

• 0m/s

You have learned all the graphs you need.

Now you must practice all of them, on how to interpret them.
