Questions & Step-by-Step Solutions
A particle moves in a straight line under the influence of a constant force of 12 N. If the particle moves 3 m, what is the work done by the force?
Step 1: Identify the force acting on the particle, which is given as 12 N.
Step 2: Identify the distance the particle moves, which is given as 3 m.
Step 3: Use the formula for work done, which is Work = Force × Distance.
Step 4: Substitute the values into the formula: Work = 12 N × 3 m.
Step 5: Calculate the result: 12 × 3 = 36.
Step 6: Conclude that the work done by the force is 36 Joules (J).
Work Done – Work done by a force is calculated as the product of the force applied and the distance moved in the direction of the force.
Constant Force – The problem involves a constant force, which simplifies the calculation of work done since the force does not change over the distance.
