100
Predict the displacement curve for the following graph:
What is...?
A positive, curved line (See mini whiteboard)
100
This is the direction that gravity always points while the force is on a free-body diagram with an object on earth's surface
What is straight down?
100
Indicate whether the object is speeding up or slowing down in the below scenario:
An object has a negative velocity and a negative acceleration
What is speeding up?
(Both vectors are pointing in the same direction!)
200
The following is a vector or a scalar. Name which of the two!:
Force
What is a vector?
200
Solve the following equation for the missing variable:
A group of bike riders took a 4.0-hour trip. During the first 3.0 hours, they traveled a total of 50. kilometers, but during the last hour they traveled only 10. kilometers. What was the group’s average speed for the entire trip?
What is 15 km/hr?
200
Predict the acceleration curve based on the following displacement graph:
What is NEGATIVE CONSTANT?
Object is slowing down. Object is not moving as far every given second, therefore acceleration must be in the opposite direction, therefore negative!
200
This term is used to describe gravity when acting on an object. It is also mass x gravitational constant
What is Weight?
200
Indicate whether the following object is speeding up or slowing down:
An object has a positive acceleration and a negative velocity
What is slowing down?
opposing directions!
300
The following is a vector or a scalar. Name which of the two!:
Time
What is a scalar?
300
Solve for the missing variable:
An airplane originally at rest on a runway accelerates uniformly at 8.0 meters per second² for 35 seconds. During this 35-second interval, the airplane travels a distance of approximately
What is 4900m?
300
Predict the acceleration graph from the following velocity vs time graph:
What is CONSTANT POSITIVE?
300
Indicate the correct Free-Body Diagram for an object in this scenario:
A car is moving to the right at constant speed on a flat road
What is...?
300
Indicate whether the following is speeding up or slowing down:
What is slowing down THEN speeding up?
Remember- Increases in the negative direction would still feel like "speeding up", you are just going the other way!
