Questions & Step-by-Step Solutions
If a force of 15 N is applied to a mass of 3 kg, what is the net force acting on the mass if there is a frictional force of 5 N opposing the motion?
Step 1: Identify the applied force. In this case, the applied force is 15 N.
Step 2: Identify the frictional force that opposes the motion. Here, the frictional force is 5 N.
Step 3: To find the net force, subtract the frictional force from the applied force. This means you calculate 15 N (applied force) - 5 N (frictional force).
Step 4: Perform the subtraction: 15 N - 5 N = 10 N.
Step 5: The result, 10 N, is the net force acting on the mass.
Net Force Calculation – Understanding how to calculate net force by subtracting opposing forces from the applied force.
Frictional Force – Recognizing the role of friction as an opposing force that affects the net force on an object.
Newton's Second Law – Applying the principles of Newton's Second Law, which relates force, mass, and acceleration.
