Which law states that an object in motion remains in motion unless an unbalanced force acts upon it.
Newton's First Law of Motion
Newton's Second Law of Motion
Which of Newton's Laws states that forces come in pairs.
Newton's Third Law of Motion
What is the unit for Force?
Newtons (N)
True or False: If an object is pushed with more force, it will have a greater change in motion (acceleration).
True
For every force that an object exerts on another object, the other object exerts an _______ amount of force back, but in the opposite direction.
equal
This term means a push or a pull.
What is force?
This is one form of the equation that represents Newton's Second Law of Motion.
What is F=ma, a=F/m, or m=F/a.
Explain how Newton's Third Law applies to the Space Shuttle launching from earth.
jet fuel combustion pushing down, thrusting the rocket up into the air
This term means that objects will remain at rest or continue in motion.
What is inertia?
According to Newton's Second Law, what happens to force if the mass is half as much ?
Force is cut in half.
Which of Newton's Laws is important for dribbling a basketball and why?
Newton's Third Law and various explainations
Explain using Newton's First Law why you must wear a seat belt.
You wear a seat belt because when you brake your car or someone hits your car, a force is applied to the car....not to YOU! According to Newton's first law, you would keep moving in the direction you were previously moving.
When a 10 kg object is being pushed by an unbalanced force of 140N, what is the acceleration?
What is 14 m/s^2?
