You push your 2 kg textbook with a constant force of 100.0 N across a surface with zero coefficient of friction. If you push the book along the tabletop as described, what is the acceleration of the textbook? Consider the 2 kg textbook, now perfectly at rest on your desktop. The force that the desktop surface exerts on the textbook is called the “normal force”. True or False?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
