Is the following a vector or a scalar:


Distance

What is a scalar?

100

Solve the following equation for the missing variable:



A horizontal 8.0-newton force applied to a 4.0-kilogram block on a frictionless table.


What is the magnitude of the block’s acceleration?

What is 2.0 m/s2?

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!

400

The following is a vector or a scalar. Name which of the two!:


Acceleration

What is a vector?

400

Solve for the missing variable:

An object is traveling in circular motion. The velocity of the car is 12.0 m/s and the radius of the circle is 2.5m. Calculate the acceleration of this object

What is 57.6 m/s2?

400

Predict the displacement curve based on the following velocity vs time graph:

What is.... Please see small white board for answer!

What is a:


Fy = 30.44 N

Fx = 39.67 N 

500

Please predict BOTH the velocity and acceleration curves for the following displacement:



THERE WILL BE 20 SECONDS AFTER I FINISH READING TO WORK BEFORE ANYONE CAN BUZZ IN! 

Please see the small boards!
