What is A push or pull that causes an object to move, stop, or change direction?
Force
force= push or pull
What is a force that acts in an opposite direction to movement?
Friction
FRICTION= opposite direction/ slows down
What is the variable that will stay the same in an experiment?
Constant Variable
constant= same
A. kicking a soccer ball
B. Opening a car door
C. Pushing a lawn mower
D. Ringing a door bell
B. Opening a car door
pull= towards you
What is the ability to cause change or do work?
Energy
energy= movement
What is a force that pulls a magnetic material across a distance
Magnetism
Magnetism= attraction of a magnet
NICS
What is the variable that is being measured or observed in an experiment?
Dependent Variable
Dependent variable= measure
Which is an example of a pushing force?
A- Lifting a heavy bag of groceries
B- Punting a football
C- Dropping a ball
D- Opening a door
B- Punting a football
push= away
What is where something is, its location?
Position
position= location
Friction is the force between two objects when they come in contact with each other. More friction occurs when an object rubs or move against what kind of surface?
A- smooth
B- rough
C- shiny
D- flat
B- rough
rough= more friction
What is the variable that you change in an experiment? ( what you are testing)
Independent Variable
When a basket ball plater dribbles a basket ball, what type of force does he put on the basketball?
A- Push
B- Pull
C- Friction
D- Gravity
A- Push
push-= away
What is how an object moves from one place to another?
Motion
motion= movement
What tool measures force and what is the unit?
A spring scale and Newton
Tool- spring scale
Newton= measurement of force
Which procedure below would provide the best data?
A- Pull each type of show once and record the results
B- Pull each type of shoe twice and record the results
C- Pull each shoe five times and record the results
D- All the procedures have the same reliability
C- Pull each shoe five times and record the results
repeated trials= more reliable
When the basketball is moving towards the ground what other force is being applied?
A- Friction
B- Gravity
C- Work
D- Magnetism
B- Gravity
Gravity= Pull down
What pulls objects to its center of the Earth? ( It keeps you grounded)
Gravity
gravity= pulls down
Rubbing your hands together creates what type of force?
A- Gravity
B- Friction
C- Pulling
D- Pushing
Friction
Friction= opposite direction
Why is it important to conduct multiple trials in a simple experimental investigation?
Repeated trails makes the experiment more reliable and accurate
What types of forces are being applied when a student is moves back and forth on a swing? What happens to their position?
Push and Pull- legs moving back and forth
Their position is being changed because work in being done to cause movement back/forth
push= away
pull= towards
