Displacement in Conversation of Energy on Incline vs Projectile

In summary, displacement in the conversation of energy on an incline refers to the change in position of an object as it moves along an inclined surface. It is a vector quantity that takes into account the direction and magnitude of the movement. In a projectile motion, displacement refers to the change in position of an object as it moves through the air due to gravity. In an incline, displacement also takes into account the change in position as the object moves along the inclined surface. Displacement plays a crucial role in the conservation of energy on an incline, as it determines the work done on the object and affects its potential and kinetic energy. It can be negative if the object moves in the opposite direction of the chosen reference point. Displacement can

How come when I do a conservation of energy up an incline the displacement is the distance up the incline, but when I do a conservation of energy from a projectile the displacement is not the resultant of the x and y displacements (instead, it's only the displacement in the y-direction)?

Thank-you

If the forces are only along y, then only y-displacement matters for work done. Look up the definition of work and of the dot product involved in it.
 

FAQ: Displacement in Conversation of Energy on Incline vs Projectile

1. What is displacement in the conversation of energy on an incline?

Displacement in the conversation of energy on an incline refers to the change in position of an object as it moves along an inclined surface. It is a vector quantity that takes into account the direction and magnitude of the movement.

2. How is displacement different in a projectile motion compared to an incline?

In a projectile motion, displacement refers to the change in position of an object as it moves through the air due to gravity. In an incline, displacement also takes into account the change in position as the object moves along the inclined surface.

3. How does displacement affect the conservation of energy on an incline?

Displacement plays a crucial role in the conservation of energy on an incline. It determines the work done on the object, which in turn affects the potential and kinetic energy of the object. The total energy of the object remains constant as long as there is no external force acting on it.

4. Can displacement be negative in the conservation of energy on an incline?

Yes, displacement can be negative in the conversation of energy on an incline. This occurs when the object moves in the opposite direction of the chosen reference point. In this case, the displacement is represented by a negative value.

5. How can we calculate displacement in the conversation of energy on an incline?

The displacement in the conversation of energy on an incline can be calculated using the distance formula, which takes into account the initial and final positions of the object. It can also be calculated by finding the difference between the final and initial velocities of the object and multiplying it by the time taken for the object to move between those two points.
