Questions & Step-by-Step Solutions
A 2 kg object is raised to a height of 5 m. What is the potential energy gained?
Step 1: Identify the mass of the object. In this case, the mass (m) is 2 kg.
Step 2: Identify the height to which the object is raised. Here, the height (h) is 5 m.
Step 3: Identify the acceleration due to gravity (g). The standard value is approximately 9.8 m/s².
Step 4: Use the formula for potential energy (PE), which is PE = m * g * h.
Step 5: Substitute the values into the formula: PE = 2 kg * 9.8 m/s² * 5 m.
Step 6: Calculate the result: 2 * 9.8 * 5 = 98 J.
Step 7: Conclude that the potential energy gained is 98 Joules.
Potential Energy – Potential energy is the energy stored in an object due to its position in a gravitational field, calculated using the formula PE = m * g * h.
