Where are you at?😎


LT: I can graph motion on a velocity/time graph from a description of the motion.

3D- INDEPENDENTLY- I understand. I can teach a friend. I can even show you more

3- INDEPENDENTLY- I understand and can do it by myself

2.5- WITH GUIDANCE- I understand most of it, I need help getting started, but I can finish by myself

2- WITH GUIDANCE- I understand some and can get started, but I'm a little confused

1.5- WITH SUPPORT- I understand a little, but I need help getting started and guidance to help me finish.

MULTIPLE CHOICE QUESTION

What is the definition of acceleration?


Choose 1 correct answer.

Speed with a direction

A constant speed over time

The change in velocity's rate over time

Returning to the original position

Answer explanation

When graphing motion, acceleration is represented by a line on a velocity/time graph. A positive or negative slope on a velocity time graph represents acceleration because the velocity is changing over time---the velocity is either increasing or decreasing respectively

A flat line of a velocity-time graph represents __________.


Choose all that apply.

positive acceleration

constant velocity

negative acceleration

no acceleration

Answer explanation

Media Image

Letter B represents a constant velocity or no acceleration because from 20s-40s, the velocity stays the same (constant) at 40 m/s

What are examples of acceleration?


Choose all that apply.

a bus speeding up

sitting in class working on Exact Path

a falcon changing direction to catch its prey

slowing down in the hallway to stop at your locker

Answer explanation

Lesson 4 on the Acceleration Notes. Acceleration is a change in velocity's rate (in speed or direction).


a bus speeding up---> = increasing velocity

a falcon changing direction--> =changes direction

slowing down in hallway---> = decreasing velocity

Media Image

Explain the motion from 1-3s.


Choose 1 correct answer.

Not moving

Constant velocity

Constant acceleration

Non-constant acceleration

Answer explanation

Media Image

The line is flat from 1s-3s and a flat line represents constant velocity or no acceleration. The reason why is the velocity (on the y-axis) stays at 8m/s at 1s, 2s, 3s, and then begins to increase after 3s.

Media Image

Explain the motion from 3-5s.


Choose all that apply.

Not moving

Positive Acceleration

Increase in velocity

Non-constant acceleration

Answer explanation

Media Image

On a velocity/time graph, the positive slope represents an increase in velocity. As time increases, velocity also increases. On a distance/time graph, the positive slope means the object is covering a distance at a constant velocity.

Media Image

Explain the motion from 5-7s.


Choose all that apply.

Deceleration

Constant speed

Negative Acceleration

Decrease in velocity

Answer explanation

Media Image

At 5s-7s the line has a negative slope. A negative slope on a velocity graph is a decrease in velocity because as the line moves downward, the velocity also decreases.
