It takes more work to lift the box because lifting against gravity requires more force than pushing along a ramp.
When lifting a box, you're increasing its potential energy by raising it against gravity, whereas when pushing it up a ramp, you're exerting force over a longer distance, which compensates for the reduced force required. Ultimately, the work done in both cases is equal because the change in potential energy is equal to the force multiplied by the distance moved in the direction of the force.
The ideal mechanical advantage of a ramp is equal to the length of the ramp divided by the vertical height it lifts an object. This ratio gives an indication of how much easier it is to move an object up the ramp compared to lifting it vertically. A higher mechanical advantage indicates a more efficient ramp design.
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.
The ideal mechanical advantage (IMA) of a ramp is typically calculated as the ratio of the length of the ramp to the vertical height it lifts objects. It represents how much easier it is to move objects up the ramp compared to lifting them vertically.
A ramp can make lifting a box easier by spreading the work over a longer distance. Instead of lifting the box straight up, you can use the ramp to slide it up gradually, which requires less force at any given moment. This allows you to achieve the same amount of work with less effort.

Reduce the friction of it and the ramp, for example, mounting it on wheels.

Increasing the height of a ramp will make it harder to push an object up the ramp, which means the effort force required to move the object will also increase. This is because the higher ramp increases the angle of incline, causing more resistance to the force applied.
MA = 5 / 0.75 = 6.67 Essentially, its the reciprocal of the sin of the ramp angle
inclined plainA ramp is an example of an inclined plane(:A ramp is an inclined planeincline planeA ramp belongs under the simple machine category of inclined planes. Inclined planes are sloping or slanting in figure which allows less effort to be exerted or applied, making work easier. The ramp has one end raised up to help raise an object, rather pushing a certain object than lifting it. Other examples of inclined planes other than the ramp are the stairs. When two inclined planes are put back to back, another simple machine called the wedge.
Using a ramp allows you to spread the force required to lift the heavy object over a longer distance, making it easier to push or pull the object up the ramp with less effort compared to lifting it straight up. This is because the ramp reduces the steepness of the incline, requiring less force to overcome gravity.
The mechanical advantage of a ramp is calculated by dividing the length of the ramp by the vertical rise. This ratio represents how much less force is required to move an object up the ramp compared to lifting it straight up. The formula for mechanical advantage of a ramp is: Mechanical Advantage = Length of ramp / Vertical rise.
A ramp makes work easier by reducing the amount of force needed to move an object between different heights. Instead of lifting the object straight up, you can push or pull it along the inclined surface of the ramp, which requires less force. This helps to minimize the work done against gravity and makes it easier to transport heavy loads.
