[Physics Tips] Always find the F(net)

student,

Welcome to another issue of Physics Tips Daily - the free eZine to provide tips and tricks for students to survive and excel in physics.

Today's topic is about the net force.

Often there will be multiple forces acting in a particular situation or problem. All of these forces must be accounted for. They must be combined to form the resultant, or net force. This is the force that you'll use to predict or describe the motion of the object it is acting upon.

For example, if you push on a stuck car with 300N for force, that doesn't necessarily mean that it is the only force acting on the car. Maybe there is also 300N of frictional force that is opposing your motion. If that's the case, then the net force on the car is 0N! The two 300 N forces cancel out to give a resultant of zero. This means your car is stuck in spite of your applied force.

Tip of the Day: Force is a vector, consider all directions!

That should do it for today.

Keep it up with your study. "See" you tomorrow.

Meanwhile, Seize the Day!
