Question image

Does the Earth have an influence on things around it?

1

Yes

2

No

3

Fill in the Blank

What is the name of this influence?

4

Fill in the Blank

Question image
What does the Earth have that allows it to have this influence?

5

Fill in the Blank

What must other objects have to allow them to be influenced by the Earth?

6

Fill in the Blank

Question image
How far does the Earth's influence extend?

Multiple Choice

Question image

Suppose an elephant and a mouse find themselves suspended near the surface of the Earth.

a. Which has a greater gravitational force acting on it?

1

elephant

2

mouse

3

same for both

8

Multiple Choice

Question image

Suppose an elephant and a mouse find themselves suspended near the surface of the Earth.

b. Which would undergo a greater acceleration if dropped?

1

elephant

2

mouse

3

same for both

9

Fill in the Blank

What is the ratio that defines the value of this acceleration?

10

Gravity

We have called this ratio gravitational acceleration.

AND we have called it gravitational field.

On earth it's 9.8 (roughly 10) and can be measured in m/s2 or N/kg.

Either way it is symbolized by g.

13

Fill in the Blank

Question image
What must other objects have to allow them to be influenced by the dome?

14

Fill in the Blank

Question image
How far does the dome's influence extend?

15

Multiple Choice

Question image

Suppose a small charge and a large charge find themselves suspended near the dome.

a. Which has a greater electric force acting on it?

1

small charge

2

large charge

3

same for both

16

Electric Field

While the force is greater on the larger charge, the force/charge is the same.

This is called Electric Field

Electric Field

  • E = F/q

  • Units are N/C

  • Often in 100,000s of N/C
