A change in direction does not change acceleration
What is false
100
When the net force is 0 N, the object is balanced
What is false
100
Earths gravity makes heavier objects fall faster then lighter object s
What is ture
100
A cork will sink when put into water
What is false
200
A change in position over time
What is motion
200
Rate at which velocity changes
What is acceleration
200
Combination of all forces acting on an object
What is net force
200
Force of attraction between objects due to their mass
What is gravity
200
The SI unit for pressure
What is pascal
300
Is speed in a specific direction
What is velocity
300
Acceleration in a circular motion
What is centripetal force
300
The tendency of all objects to resist a change in motion
What is inertia
300
An object that travels around another object in space
What is orbit
300
The measure for force is acting on a given area
What is pressure
400
How are distance, time, and speed related
What is distance and time are what make up speed
400
How does motion change
What is a change in position or acceleration
400
How do forces affect motion
What is: forces are what cause a motion the happen
400
How do objects move under the influence of gravity
What is objects move due to their weight.
Light- move easier
Heavy- move harder
400
What happens when fluids exert pressure
What is pressure gets higher as fluids add up more and more
500
Henry lives 100 m away from Bill. What is Henry's average speed of he reaches bills home in 50 s?
What is 2 m/s
500
What is the acceleration experienced by a car that takes 10 s to reach 27 m/s from rest. Explain.
What is 2.7 m/s. You take final velocity and subtract it from starting velocity and then divide it by the time which is 10 seconds.
500
How do you determine net force?
What is you add all the forces that are acting on an object and you will get your net force
500
What 2 motions combine to produce an orbit? Explain
What is a pulling motion towards and object and a motion pulling it diagonally away from the object. This is just like our world. The sun pulls us towards it while another force pulls away from the moon in a diagonal way.

Explain why atmospheric pressure changes as atmospheric depth changes
What is because as you go deeper under water, the higher the amount of volume is on top of you, causing the pressure around you to increase.
