Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following statements best describes net force?
The total force acting on an object.
The unbalanced force that causes acceleration.
The force of gravity on an object.
The resistance to motion.
2. According to Newton's Second Law of Motion, what is the relationship between force, mass, and acceleration?
Force = mass + acceleration
Force = mass / acceleration
Force = mass × acceleration
Force = acceleration - mass
1. When the net force acting on an object is zero, the object's acceleration is .
2. The unit of force in the International System of Units (SI) is the .
3. An object with a larger mass will have a acceleration when acted upon by the same net force.
1. Explain the difference between balanced and unbalanced forces. How do they relate to an object's motion?
2. A car with a mass of 1200 kg accelerates at 2.5 m/s². Calculate the net force acting on the car.
1. An object can be moving at a constant velocity even if there is a net force acting on it.
True
False
2. If you push on a wall with 50 N of force, and the wall does not move, the net force on the wall is 50 N.
True
False
