12 questions

Question 1

Explain the difference between the mass of an object, and the weight of an object.

Question 2

If Student #2 has a Weight of 1204 N, what is their mass in kg? (rounded to hundreths)

Question 3

A downward-moving skydiver who has just opened the parachute is slowing down. Diagram the forces on the skydiver/parachute combination. (Grading on forces and magnitudes)

Question 4

A football is moving upward and rightward towards the peak of its trajectory. Ignore the air resistance. (Grading on forces and magnitudes)

Question 5

A rightward force is applied to a dresser to accelerate it to the right across the bedroom floor. Ignore the air resistance. (Grading on forces and magnitudes)

Question 6

The _______ is the vector _______ of all the _______ that act upon an object.

Question 7

Is there a net force acting upon this object?

Yes

No

Question 8

Explain your answer.

Question 9

Why does constant velocity indicate NO net force?

net forces are connected to velocity, not acceleration

constant velocity means that there is acceleration, and therefore means that there is no net force

for something to be moving at a constant velocity means there must be a force acting upon it somewhere (Mr. Fischers Example of the Laptop Case)

constant velocity means no acceleration, and for there to be a net force there must be acceleration

Question 10

10.

What is the net force on the object?

Question 11

11.

Explain what is happening to the object using the word 'acceleration'.

Question 12

12.

In the situation above, the force of letter D must be _______ Newtons, and letter E must be pulling with a force of _______ Newtons.
