Force
The push or pull on an object.
What is force?
Newton’s discoveries about how motion always works.
What are Laws of Motion?
Factors that give an object the amount of moving energy it has.
What are mass, speed, and direction?
Having two opposite sides that work differently.
What is polarity?
A device that makes work easier.
What is a machine?
Movement resulting from force.
What is work?
The property of matter that makes it resist a change in motion.
What is inertia?
Energy suddenly transferred from one object to another.
What is a collision?
The attracting force between two objects.
What is gravity?
A machine that helps to overcome friction because of its rolling action.
What is a wheel and axle?
Opposing forces that prevent work from being done.
What are balanced forces?
This determines the amount of inertia an object has?
What is an object's mass?
During a collision, this happens to the objects' moving energy.
What is a change is speed?
The strongest parts of a magnet.
What are its poles?
A machine that gives you a slope on which to push upward.
What is an inclined plane?
A greater force that overcomes opposing forces, resulting in work.
What are unbalanced forces?
Finish this statement: An item at rest tends to.
What is stay at rest unless acted upon by an unbalanced force?
During a collision, moving energy becomes heat and sound energy.
What is converted energy?
The force of gravity on an object.
What is weight?
A machine that can be used to lift heavy things.
What is a pulley?
A force that works against motion along a surface.
What is friction?
Finish this statement: An object in motion will move in a straight line at a constant speed unless..
What is acted upon by an unbalance force?
The most stable shape.
What is an upright pyramid?
A device that generates electromagnetic force.
What is an electromagnet?
Type of inclined plane often used with a drill.
What is a screw?
