What's your Friction?
A Force of Attraction
Rhyme Time
100
An object that appears to remain in one place is called this.
What is a reference point?
100
All forces have these two properties.
What is direction and size?
100
This is the force that opposes the motion between two surface that touch.
What is Friction?
100
This is force of attraction, or pull, between objects.
What is Gravity?
100
This rhymes with SELL but means you tripped.
What is FELL?
200
You can use standard reference directions to describe an object's motion. List three of them.
What is north, south, east, west, etc?
200
You determine this when all the forces acting on an object are added together.
What is Net Force?
200
This type of friction occurs when force is applied to an object and the object moves.
What is Kinetic Friction?
200
Newton's ideas about all objects in the world being attracted to one another as result of gravitational force is called this.
What is Law of Universal Gravitation?
200
This rhymes with BLAME but means it can burn you.
What is FLAME?
300
This is the rate at which an object moves.
What is Speed?
300
Predict: This would happen if two dogs pulled a rope with a force of 100 N (in opposite directions).
What is there will be a net force of zero and there will be no movement.
300
This is a substance that reduces the friction between surfaces.
What is a Lubricant?
300
This word means that a law applies to all objects.
What is universal?
300
This rhymes with BLOCK but it helps you tell time.
What is Clock?
400
This is the speed of an object and its direction.
What is velocity?
400
This type of force produces a change in motion of an object.
What is unbalanced force?
400
True or False: One can increase friction by adding grease to a surface. Why?
What is False?
400
This is a measure of the gravitational force of an object.
What is weight?
400
This rhymes with STING but it's something you put on your hand.
What is RING?
500
This is how quickly velocity changes.
What is acceleration?
500
Predict: This would happen to an object that has an unbalanced force acting on it.
What is it will move in the direction of the greatest force?
500
True or False: Static friction occurs when the force applied to an object causes it to move.
What is False?
500
This is the measure of the amount of matter in object.
What is Mass?
500
This rhymes with PAT but it's a sound of something falling.
What is SPLAT?
