<p>Work in physics is the energy transferred to or from an object via the application of force along a displacement. It is calculated as the product of the force strength and the distance traveled. For example, when a ball is dropped, the work done by the gravitational force is positive, and is equal to the weight of the ball multiplied by the distance to the ground. If the ball is thrown upwards, the work done by the gravitational force is negative, and is equal to the weight multiplied by the displacement in the upwards direction.</p> Signup and view all the answers

<p>A force does positive work when it has a component in the direction of the displacement at the point of application. For example, when a ball is dropped, the work done by the gravitational force is positive as it is aligned with the direction of motion.</p> Signup and view all the answers

<p>A force does negative work when it has a component opposite to the direction of the displacement at the point of application. For example, when a ball is thrown upwards, the work done by the gravitational force is negative.</p> Signup and view all the answers

<p>The work done by the gravitational force on a falling ball is positive, equal to the weight of the ball multiplied by the distance to the ground. When the ball is thrown upwards, the work done by the gravitational force is negative, equal to the weight multiplied by the displacement in the upwards direction.</p> Signup and view all the answers

<p>When a force is applied in the direction of displacement, the work done is calculated as the product of the magnitude of the force and the displacement, represented by the equation $W = F \cdot d$.</p> Signup and view all the answers
