Questions & Step-by-Step Solutions
A 10 kg object is pushed with a force of 30 N. If the frictional force is 10 N, what is the net force?
Step 1: Identify the applied force. In this case, the applied force is 30 N.
Step 2: Identify the frictional force. Here, the frictional force is 10 N.
Step 3: Use the formula for net force, which is: Net force = Applied force - Frictional force.
Step 4: Substitute the values into the formula: Net force = 30 N - 10 N.
Step 5: Calculate the net force: 30 N - 10 N = 20 N.
Net Force Calculation – Understanding how to calculate net force by subtracting frictional force from the applied force.
Newton's Second Law – Application of Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.
