One is the scalar value of how far an object has traveled regardless of direction. The other is the vector value of how how far and object is from where it started and it's direction.
What is the difference between distance and displacement?
100
Every object in motion will stay in motion at a constant rate and every object at rest will stay at rest unless acted upon by and unbalanced force.
What is Newton's First Law of motion?
100
9.8 m/s/s
What is the acceleration due to gravity?
100
This is energy that is not currently in use; it is stored. The object has received energy due to its position in the world. ____ = mgh is the formula.
What is potential energy? What is the formula?
100
This is the amount of force applied to an object (in the same direction as the motion) over a distance. It is measured in Joules or Newton-Meters. The formula is _____ = F*d.
What is work? What is it measured in? What is the formula?
200
One is the distance traveled by an object divided by the total time regardless of direction and the other is the distance/time in regard to direction.
What is the difference between speed and velocity?
200
The force (1 Newton) required to accelerate 1 kg of mass at a rate of 1 m/s/s.
Define Newton's Second Law of Motion.
200
The force in opposition to motion. Due to this force the motion of an object may slow down or even stop.
What is friction?
200
This is the energy that an object in motion has. It is directly proportionate to the speed and mass of the object in motion. _____=1/2MV^2 is the formula.
What is kinetic energy? What is the formula?
200
This is the rate at which energy is transferred, used or transformed. It is measured in watts, kilowatts, or horsepower. The formula is ____ = W/t.
What is power? What is it measured in? What is the formula?
300
This is the displacement of an object divided by it's time. Direction is a factor.
What is acceleration?
300
Every action has an opposite and equal reaction.
What is Newton's Third of Motion?
300
Static, rolling, fluid, and sliding.
What are the four types of friction?
300
This force the amount objects are attracted to the center to the Earth. Both mass and distance are big factors in determining the amount of this force there will be.
What is gravity?
300
Solve: A woman lifts her 100 Newton child up one meter and carries her for a distance of 50m to the child's bedroom. How much work does the woman do?
Work = 5,000 Joules or Newton-Meters
400
Solve: A train that is travelling at a rate of 9 m/s has accelerated by 5 m/s/s for 20 seconds. What is the distance it has covered?
Distance = 1,180 m
400
Solve: What is the force that a tortoise is exerting as it is pushing a 50,000 kg box at a rate of 0.08 m/s/s?
Force = 4,000 Newtons
400
This is the force that tries to bring all objects in motion towards the center of activity and into a circular "orbit".
What is centripetal force?
400
ME = PE + KE
What is the formula for mechanical energy?
400
A horse moves a sleigh 1 kilometer by applying a horizontal 200 newton force on its harness for 45 mins. What is the power of the horse?
Power = 740.74 watts
500
Solve: A baby running a marathon started with a velocity of 20 m/s and ended with a velocity of 50 m/s. He ran the entire marathon in 40 seconds. What was the baby's acceleration?
Acceleration = 0.75 m/s/s
500
Swimming in a pool is an example of this law of motion because as one pushes against the water (action) one is propelled forward as a reaction.
What is an example of Newton's 3rd Law of Motion? Why is it so?
500
The force of fluids that push objects up and make them seem to loose weight.
Define Buoyancy.
500
1) A ball when thrown up in the air
2) A person running
What are two examples of Kinetic Energy?
500
A microwave uses 72,000 joules of energy in 60 seconds.
What is the power of the microwave?
