### What is the equation for work done by a constant force?

$W = Fd \cos(\theta)$

### When does a force do negative work?

When it has a component opposite to the direction of the displacement

### What is the work done by the gravitational force when a ball is thrown upwards?

Negative and equal to the weight multiplied by the displacement in the upwards direction

### What happens to the work done by the gravitational force on a ball as it falls towards the ground?

It is positive and equal to the weight of the ball multiplied by the distance to the ground

### In the work equation $W = Fd \cos(\theta)$, what does $\theta$ represent?

The angle between the force and the displacement vectors

Positive

### In its simplest form, work for a constant force aligned with the direction of motion equals the product of:

Force strength and distance traveled

Negative

Negative

### The work done by the gravitational force on a ball as it falls is equal to:

The weight of the ball multiplied by the distance to the ground

### When does a force do negative work?

When it has a component opposite to the direction of the displacement at the point of application

### What is the work done by the gravitational force when a ball is held above the ground and then dropped?

Positive, equal to the weight of the ball multiplied by the distance to the ground
