Questions & Step-by-Step Solutions
If a force of 30 N is applied to a mass of 10 kg, what is the net force acting on the mass if there is a frictional force of 10 N opposing the motion?
Correct Answer: 20 N
Step 1: Identify the applied force. In this case, the applied force is 30 N.
Step 2: Identify the frictional force that opposes the motion. Here, the frictional force is 10 N.
Step 3: To find the net force, subtract the frictional force from the applied force. This means you take 30 N (applied force) and subtract 10 N (frictional force).
Step 4: Calculate the net force: 30 N - 10 N = 20 N.
Step 5: The net force acting on the mass is 20 N.
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.
