Questions and Answers

What type of work does the gravitational force do on a ball as it falls?

No work

Negative work

Variable work

Positive work (correct)

What is the equation for work in its simplest form for a constant force aligned with the direction of motion?

$W = F + d$

$W = F \cdot d$ (correct)

$W = F - d$

$W = \frac{F}{d}$

When does a force do positive work?

When it has a component opposite to the displacement

When it has no component in the direction of the displacement

When it has a component perpendicular to the displacement

When it has a component in the direction of the displacement (correct)
