For every action there is an equal and opposite reaction.
What is Newton's 3rd Law of Motion?
100
The force that objects exert on each other because of their mass.
What is gravity?
100
The use of force to move an object over a distance.
What is work?
100
A doorknob.
What is an example of a wheel and Axle?
200
a baseball being dropped.
What is an example of a projectile?
200
An object at rest will remain at rest an and object in motion will remain in motion until an unbalanced force acts upon it.
What is Newton's 1st Law of Motion?
200
A force that resists the motion between two surfaces in contact.
What is Friction?
200
W=F X D
What is the formula to calculate work?
200
Teeter Totter.
What is an example of a lever?
300
a car being driven.
What is an example of straight-line motion.
300
The greater the mass of the object the weaker the acceleration and the greater the force applied to an object the greater the acceleration.
What is Newton's 2nd Law of Motion?
300
The force of gravity gets weaker.
What happens when the distance between two objects gets larger or the mass gets smaller?
300
Pushing on a wall for hours but the wall does not budge.
What is an example of work not being done?
300
A wheel with a grooved rim that turns on an axle.
What is a pulley?
400
An earthquake.
What is an example of vibrational motion?
400
Law of acceleration or Force=Mass X Acceleration
What is another name for Newton's 2nd Law of Motion?
400
The force of gravity increases?
What happens when the distance between two objects gets smaller or the mass of the objects increases?
400
Turning a page in a book.
What is an example of work being done?
400
Because some input force is always lost, usually due to friction.
Why is it impossible to have a machine that is 100% efficient?
500
Distance/Time
What is the formula for speed
500
Inertia
What is another name for Newton's 1st Law of motion?
500
All objects exert a force of gravity on all other objects. In order for the force of gravity to be great the distance must be small and the mass must be great.
What is the Law of Universal Gravitation?
500
Find the amount of work done. A box is moved with 5N of force a distance of 6m.
What is 30 J
500
The number of times a machine multiplies the input force.
