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

What is the work done by a force when it has a component in the direction of the displacement?

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

When a force has a component opposite to the direction of the displacement, the work done is:

Negative

If a ball is thrown upwards, the work done by the gravitational force is:

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

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

The angle between the force and the displacement vectors

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

It is positive

For a constant force aligned with the direction of motion, the work equals:

The product of the force strength and the distance traveled
