According to Newton's Second Law, what is the effect of applying a net force on an object?

The object accelerates in the direction of the net force. The acceleration is directly proportional to the net force and inversely proportional to the mass (F=maF = maF=ma).

According to Newton's Second Law, what is the effect of applying a net force on an object?

The object accelerates in the direction of the net force. The acceleration is directly proportional to the net force and inversely proportional to the mass (F=maF = maF=ma).

What is the effect of the Earth pulling on you?

You pull on the Earth (equal and opposite force).

What are the general steps to solve a problem using forces?

  1. Draw a Free-Body Diagram (FBD). 2. Identify all forces acting on the object. 3. Calculate the net force. 4. Apply Newton's Second Law (F=maF=maF=ma) to find acceleration.

How do you determine the resultant force when multiple forces are acting on an object?

  1. Represent each force as a vector. 2. Add the force vectors together, considering both magnitude and direction. 3. The resulting vector is the resultant force.

Identify the forces acting on the box in the Free Body Diagram.

1: Weight (Force of Gravity), 2: Normal Force, 3: Applied Force, 4: Force of Friction
