Read each question carefully and provide your best answer. Show all your work for calculation problems.
1. Which of Newton's Laws of Motion states that an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force?
First Law
Second Law
Third Law
Law of Gravity
2. What is the unit of force in the International System of Units (SI)?
Joule (J)
Watt (W)
Newton (N)
Kilogram (kg)
1. The tendency of an object to resist changes in its state of motion is called .
2. According to Newton's Second Law, Force equals times acceleration.
3. The force that opposes motion between two surfaces in contact is known as .
1. State Newton's Third Law of Motion and provide a real-world example.
2. Differentiate between mass and weight.
1. An object with greater mass will always accelerate faster than an object with less mass when the same net force is applied.
True
False
2. A balanced force results in a change in an object's velocity.
True
False
1. A 15 kg object is subjected to a net force of 45 N. Calculate the acceleration of the object.
2. A car accelerates from rest to 20 m/s in 5 seconds. If the mass of the car is 1200 kg, what is the net force acting on the car?
