Questions & Step-by-Step Solutions
A 2 kg object is pushed with a force of 10 N over a distance of 5 m. What is the work done on the object?
Step 1: Identify the force applied to the object, which is 10 N.
Step 2: Identify the distance over which the object is pushed, which is 5 m.
Step 3: Use the formula for work done, which is Work = Force * Distance.
Step 4: Substitute the values into the formula: Work = 10 N * 5 m.
Step 5: Calculate the result: 10 N * 5 m = 50 J.
Step 6: Conclude that the work done on the object is 50 Joules.
Work – Work is defined as the product of the force applied to an object and the distance over which that force is applied, measured in joules (J).
Newton's Second Law – Understanding the relationship between force, mass, and acceleration, although not directly needed for this question, is fundamental in physics.
