Work only occurs when an object moves in the same this as the force.
What is DIRECTION?
There are this many simple machines.
What is 6?
What is the speed?
Newton's 1st law deals with this.
What is inertia?
This much force is required to accelerate a 66kg skier at 2 m/s2.
What is 132 Newtons?
What is force and distance?
This simple machine is made of two inclined planes that separate an object.
What is the wedge?
This is the difference between velocity and speed.
This formula comes from Newton's 2nd law.
What is F = ma?
A 50 kg skater accelerates 5 m/s2 when pushed by a friend. The friend exerted this much force.
What is 250 Newtons?
This is the unit for work, also known as a NewtonMeter.
What is the Joule?
This simple machine helps most when lifting things from one height to a higher height and is often slanted.
What is the Inclined Plane?
When velocity changes in a certain time period, either by the speed changing up or down or the direction changing, it is this.
What is acceleration?
When one force acts on an object, there is an equal and opposite force that pushes back on that force.
Tommy does 15 Joules of work to push the pencil 1 meter. He used this much force.
What is 15 Newtons?
This is the amount of work an elephant does while moving a circus wagon 20 meters with a pulling force of 200 N.
What is 4,000 Joules?
These are combinations of simple machines.
What are Compound Machines?
When Jane took 45 minutes to bicycle 4km to her aunt’s house, her velocity in km/hr? (Hint you have to do one time conversion from minutes to an hour. (There are 60 minutes in an hour.)
What is 5.33 km/hr?
Unbalanced forces cause an object at rest to do this.
What is move?
A girl is pedaling her bicycle at a speed of 0.10km/min. She will travel this far in 40 minutes.
What is 4km?
This is the amount of force the player used to hit the ball when there was 1234 Joules of work done over a distance of 100 meters away from home plate.
What is 12.34 Newtons?
If I am trying to move a heavy object from one side of the yard to another, I might use something with this simple machine.
What is the wheel and axle?
This is the velocity of a car that traveled 75 km north in 1.5 hours. (Hint: your answer should be in km/hr with a direction.)
What is 50 km/hr north?
This law tells why a person in a car that has just stopped will keep going.
What is Newton's 1st law?
Beth and Bob do 45,000 Joules of work when moving a heavy piece of furniture (300N) across this distance.
What is 150 meters?
