Vocabulary
This quantity of motion is defined as the product of an object's mass and velocity.
What is Momentum?
This SI unit for work.
What is a joule?
This principle states that for every action there is an equal and opposite reaction.
What is Newton's third law of motion?
The velocity of an object that traveled 19 meters in 2.0 seconds.
What is 9.5 meters/second
v=d/t =(19m)/(2s
This famous scientists teachings dominated scientific thought for almost two thousand years.
Who is Aristotle?
The velocity at which air resistance stops a falling object from accelerating.
What is terminal velocity?
Newton's second law of motion
What is
F=ma
This principle states that the velocity of an object does not change unless the object is acted upon by an external force.
What is Newton's first law of motion?
A crate was being pushed to the left by one person with a force of 35N and to the right by another person with a force of 26N. What is the net force acting on the crate?
9N to the left
=35N to the left + (-26N to the right)
=9N to the left
This famous scientist discovered the laws of motion and gravitation, laying the foundation for much of modern physical science.
Who is Sir Isaac Newton?
This mathematical quantity has both magnitude and direction.
What is a vector?
The relationship between free-fall distance and the acceleration of gravity.
What is
d=1/2 g t ^2
This principle states that the force required to accelerate an object at a certain rate equals the object's mass times the desired acceleration.
What is Newton's second law of motion?
The momentum of a 5kg bowling ball rolling forward at 7m/s.
What is 35kg*m/s?
p=mv
p=(5kg)(7m/s)
p=35kg*m/s
This scientist recognized that motion can be described in terms of speed, velocity, and acceleration.
Who is Galileo?
This is the space relative to which motion is measured.
What is the frame of reference?
The weight of an object found using Newton's second law and gravity.
What is
Fw=mg
Sir Isaac Newton published his laws of motion in this book.
What is Philosophiae Naturalis Principia Mathematica more simply referred to as Principia?
What is the total displacement of a person who walked 137m North and then 39m south?
What is 98m North?
137m North + (-39m South)
=98m North
The SI unit for power is the watt named after this famous scientist.
Who is James Watt?
The center seeking force that causes an object to travel in a curved pattern.
What is centripetal force?
The measure of how quickly an object moves.
What is
v=d/t
This quantity represents any change in an objects position.
What is displacement?
The force required to accelerate a 180,000kg train engine at a rate of 2.0 m/s
What is 360,000N.
F=ma
=(180,000kg)(2.0m/s2)
=360,000N
The SI unit of work is the joule, named after this famous scientist.
Who is James Prescott Joule?
The sum of two or more vectors.
What is a resultant?
The momentum of an object.
What is p=mv
When no net force is applied to a moving object, it still comes to rest because of its inertia. (True or False)
What is False?
Calculate the weight of a 180000kg train engine.
What is 1,770,000N?
Fw=mg
=(180000kg)(9.81m/s2)
=1,770,000N
This famous scientist made many significant innovations and discoveries including the incandescent light and the motion picture camera.
Who is Thomas Edison?
