Force 2
Real World Applications
100
A force that moves an object away.
What is a push?
100
These are the two poles in a magnet
What are North and South?
100
A certain place.
What is position?
100
This is a unit that we use to measure force.
What is Newton?
100
During a rock slide, rocks are pulled down a hill. What is the force pulling down the rocks?
What is gravitational force?
200
A force that moves an object towards another object.
What is a pull?
200
The space all around a magnet where the force of the magnet can act.
What is magnetic field?
200
The size of this type of force depends on the mass of the objects and how far apart they are.
What is gravitational force?
200
This tool can be used to measure force.
What is a Spring Scale?
200
A compass uses this type of force to locate North.
What is magnetic force?
300
A force produced by magnets.
What is magnetism?
300
This is what happens when two opposite poles are placed near each other.
What is attract?
300
This type of force is strongest at the ends of its poles.
What is magnetic force?
300
Increasing a force on an object will likely increase:
What is speed?
300
Explain why roads are made from smooth and slick materials and not carpet.
Carpet would create a lot of FRICTION (must use this word) and cars would most be able to move as easily.
400
A force that pulls all objects toward each other.
What is gravity?
400
This is what occurs when two like poles are placed near each other.
What is repel?
400
When forces on an object are _____ there is no acceleration, and the object will not move.
What is balanced?
400
A surface of an object will affect the amount of this.
What is friction?
400
When building a ramp, what are two things to consider to make a car go faster?
What are surface (affects friction) and height (affects gravity)?
500
A force that keeps objects that are touching each other from sliding past each other easily.
What is friction?
500
Most of these types of objects are attracted by magnets.
What are metals?
500
When forces on an object are _____ there is acceleration, and the object will move.
What is unbalanced?
500
Force can cause change to: (3 things)
What is speed, direction, and movement? (must answer all 3 for points)
500
What is the difference between the mass and weight of an object in space?
Mass never changes, Weight is affected by gravity. Our weight would be less, our mass would not change.
