These are two ways to increase pressure
What are decrease the area and increase the force
100
This is the weight of a 10kg object
What is 100N
100
These are two types of friction
What are kinetic friction and static friction
100
m/s2 is the unit for this measurement
what is acceleration
100
This is the unit for gravitational force
What is Newtons
200
This a is a tool used to measure pressure
What is a barometer
200
This is the amount of gravitational force on something
What is weight
200
This is what making an object lighter does to the friction.
What is decreases the amount of friction
200
This is how far a object moving at 10m/s goes in 2 seconds.
What is 20m
200
This is a property of matter describing Newton's first law that still objects wanting to stay still and moving objects wanting to keep moving
What is inertia
300
Wind is caused from air moving from areas of ________ pressure to areas of __________ pressure
What are high to low
300
These are two ways to decrease the gravity between 2 objects
What are move them further apart and make them have less mass
300
This force always goes in the opposite direction of an object's motion
What is the force of friction
300
This is Newton's 3rd law of motion
What is for every action there is an equal and opposite reaction.
300
Which is usually higher: Static friction or kinetic friction?
Static friction
400
Is there more or less pressure the further down you dive in the water?
There is more
400
Is there more gravity between the sun and the moon, or between the earth and the moon?
More between the earth and the moon
400
If you are pushing on a 40kg object with 20N of force and it doesn't move, how much static friction is there?
What is 20N
400
This is the force which balances with gravity for a non-moving object on the ground
What is normal force
400
This is the amount of atomospheric pressure we feel most of the time. (hint: the unit is atmospheres)
What is 1 atmosphere
500
A 5kg object has area of 10cm2 while sitting on a table. What is the pressure the object puts on the table?
What is 5N/cm2
500
In a vacuum a 10kg object falls to the earth at 10m/s2. How fast would a 5kg object fall to the earth in the same vacuum?
What is 10m/s2
500
If an object in the picture is moving at constant speed, how much friction force is there?
What is 40N
500
A 3kg object is falling in the air and has 30N of air friction moving against it. Is the object accelerating
What is no, the forces are balanced
500
This is the prediction of the results of a lab (spelling matters)
What is a hypothesis
