Question 1

1.

This is a position vs time graph. is the man walking faster or slower in the green section compared to the red section?

Green is faster

red is faster

they are the same speed.

Question 2

2.

Question 3

3.

what is the farthest distance the walker gets from his starting point?

Question 4

4.

Plug and chug time. You are on earth and you toss a ball up in the air with the initial velocity of 4 m/s. The ball starts 1 meter from the ground. How long does it take to hit the ground. given the following equation? use -10 m/s^2 for the acceleration due to gravity.

Question 5

Question 6

Question 7

7.

Which of these is the best definition of inertia?

How hard something is to rotate

the tendency to resist a change in velocity

A force that acts on all matter

the reason there is a pause before something starts falling

Question 8

8.

Mass is simply a measurement of inertia. What is the definition of mass?

How heavy something is

how much something resists acceleration

how much space something takes up

the quantity of molecules making up an object

Question 9

9.

Which of the following is a good example of Newton's first law of motion?

a rocket launching into space

a ball rolling down a hill

a car accelerating along a straight road

a book resting on a table

Question 10

10.

Some people (such as me) will state newton's first law as a "unbalanced" external force rather than a "net" force. What does unbalanced mean here?

Question 11

11.

Read in your physics book the following 56-62, the sections on Newton's first law, mass, and newtons second law of motion. the first two sections should re-ieterate the last video. Focus on the section on the second law. do you have any questions?

Question 12

12.

Question 13

13.

If an object has no acceleration, does that mean there are no forces on the object? explain why or why not?

Question 14

14.

What is the difference between weight and mass?

Question 15

15.

true/false - and object with mass can have no weight

True

False

Question 16

16.

Question 17

17.

Question 18

18.

A 400 kg bear is grasping a vertical tree slides down at a constant velocity. What is the friction force that acts on the bear?

the force of gravity on the bear is $400kg \cdot -10m/s^2$, we know the friction force = +4000 kgm/s^2 because the sum of forces has to be zero since there is no acceleration
