Questions & Step-by-Step Solutions
A force of 15 N is applied to a 3 kg object. What is the net force acting on the object if it is also experiencing a frictional force of 5 N?
Step 1: Identify the applied force on the object, which is 15 N.
Step 2: Identify the frictional force acting against the motion of the object, which is 5 N.
Step 3: To find the net force, subtract the frictional force from the applied force.
Step 4: Calculate the net force: 15 N (applied force) - 5 N (frictional force) = 10 N.
Step 5: The net force acting on the object is 10 N.
Net Force Calculation – Understanding how to calculate the net force acting on an object by considering both applied forces and opposing forces such as friction.
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.
