Multiple Choice

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?

• elephant

• mouse

• same for both

Multiple Choice

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

b. Which would undergo a greater acceleration if dropped?

• elephant

• mouse

• same for both

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.

Multiple Choice

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

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

• small charge

• large charge

• same for both

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
