1. Work Done Formula: - The formula for work done Work is given by: Work = Force x Distance x cos(θ) - It calculates the amount of energy transferred when a force causes an object to move a certain distance. 2. Force in the Same Direction: - When a force and the direction of an object's movement areRead more
1. Work Done Formula:
– The formula for work done Work is given by:
Work = Force x Distance x cos(θ)
– It calculates the amount of energy transferred when a force causes an object to move a certain distance.
2. Force in the Same Direction:
– When a force and the direction of an object’s movement are the same, the angle θ between them is 0°
– The cosine of 0° is 1(cos(0°) = 1 ), so Work = Force x Distance x 1
3. **Simplified Expression:**
– For a force acting in the direction of displacement, the expression simplifies to Work = Force x Distance.
4. Interpretation:
– This formula shows that when a force is applied in the same direction as the displacement, the work done is directly proportional to both the force applied and the distance the object moves.
Understanding this formula helps us calculate the work done when a force is applied to an object and it moves in the same direction as the force. In such cases, the work done can be calculated straightforwardly using the force applied and the distance covered by the object.
1. Amount of Energy Transferred: - 1 joule (1 J) of work represents the amount of energy transferred when a force is exerted on an object. 2. Force and Distance Relation: - It is defined as the work done when a force of 1 newton is applied to an object, causing it to move a distance of 1 meter in thRead more
1. Amount of Energy Transferred:
– 1 joule (1 J) of work represents the amount of energy transferred when a force is exerted on an object.
2. Force and Distance Relation:
– It is defined as the work done when a force of 1 newton is applied to an object, causing it to move a distance of 1 meter in the direction of the force.
3. Quantifying Work:
– 1 joule of work is the standard unit used to measure energy transfer and mechanical work in physics.
4. Practical Example:
– Performing 1 joule of work could involve exerting a force of 1 newton to move an object a distance of 1 meter in the direction of that force.
Understanding the concept of 1 joule helps in measuring and quantifying the amount of work or energy transferred when a force acts upon an object, causing it to move in the direction of the force.
