An example of doing work is lifting a box from the ground to a shelf. In this scenario, work is being done against gravity to move the box vertically.
An example of doing work is lifting a box from the floor to a shelf. In this scenario, you are exerting a force to move the box against the force of gravity, thereby performing mechanical work on the box.
False. Rolling a cart up a ramp is an example of doing positive work. Work is done when a force is applied to move an object in the direction of the force, such as lifting a weight or pushing a cart uphill.
False. ApEx C;
No, rolling a cart up a ramp is an example of doing positive work, as energy is being transferred to the cart to lift it against gravity. Negative work would be done if the cart were rolling down the ramp, as energy would be lost against gravity.
"Negative work" is defined as energy exerted in the opposite direction from the displacement of the object. So here, in addition to adding to the gravitational potential energy, the work is positive.

a solution example is ... you will be doing a experiment and you would try to make a solution work to make the experiment successful
No, work is a transfer of energy since the boy is just holding the book he is not doing work if he were to slide the book or throw the book for example he would be transferring energy in result "doing work".

This will depend on what the "work" is. Example, if the vehicle is in neutral gear, on low rpm idling of course the engine is doing less work. But when the accelerator is pressed to rev up, then the engine is doing more work. Another example, cruising on a flat highway at high speed but engine's rpm is low when at top gear, hence engine is doing average work. But let the vehicle go up an incline and speed goes slow and the engine's rev goes high when on first gear, hence the engine is doing a lot of work.
yes, BP is a really good example of a primary sector business so i think that its a good choice to do some work on this example if you are doing assessments on it.

An example of motion where work is done is pushing a box across the floor. When you apply a force to move the box a certain distance, you are exerting energy to overcome friction and move the box, thus doing work on the box.
