Step 1

First, we need to find the force required to lift the pumpkin. This is equal to the weight of the pumpkin, which can be calculated using the formula: weight = mass × gravity. The mass of the pumpkin is 3.2 kg, and the acceleration due to gravity is approximately Show more…

Key Concepts

Work

Work is a measure of energy transfer that occurs when an object is moved over a distance by an applied force. It is calculated using the formula W = F * d * cos(?), where F is the force applied, d is the displacement of the object, and ? is the angle between the force and the displacement direction. In cases where the force and displacement are in the same direction, the work done is simply the product of the force and the displacement.

Gravitational Potential Energy

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. It is calculated using the formula U = m * g * h, where m is the mass of the object, g is the acceleration due to gravity, and h is the height change. This energy represents the work done against the gravitational force to raise the object to a certain height.
