Dune
Which area would experience the most erosion from waves?
A
B
C
D
Sediments being deposited at the mouths of rivers creates -
Deltas
Mid-ocean ridges
Canyons
Craters
Waves erode and change the shape of -
Coastlines
Canyon walls
Crater rims
Deltas
What will most likely happen to a crater as the rim erodes?
It become deeper
It becomes shallower
It becomes wider
It becomes narrower
Dunes are mounds of sand that are created by -
Strong winds
Warm ocean water
Precipitation such as rain, snow and sleet
Gravity
In which direction and with how much force will an object move if you push to the left with 15N of force and your friend pushes to the right with 5N of force?
up with 10N of force
down with 5N of force
left with 10N of force
right with 10N of force
Which of these is evidence that an unbalanced force is acting on an object?
The mass of the object is changing
The object continues moving in a straight line
The object remains at rest
The motion of the object is changing
Newton's First Law States........
Objects at rest tend to stay at rest unless acted on by an outside force.
Objects accelerate often and it is difficult to know when or how they will accelerate.
Objects in motion tend to stay in motion unless acted on by an outside force.
Both A & C
What is inertia?
An object that is accelerating
Gravitational force
An objects tendency to stay at rest or in motion
An unbalanced force
Newton's second law states.....
If there is more mass then there is more acceleration
An object at rest wants to be in motion
Force = Mass x Acceleration
The force exerted on an object is not related to mass or acceleration
What formula is used to calculate force?
Acceleration = Force x Mass
Force = Mass x Acceleration
Work = Force x Distance
Mass = Force + Acceleration

20N
500 M/S
500 Kg
500N
A force of 40 N acts upon a 2 kg block. Calculate the acceleration of the object.

80 m/s
Newton's third law states.......
For each action there is a larger reaction associated with it.
None of these choices
For each action there is an equal and opposite reaction.
For each action there is a smaller reaction associated with it.
Forces that are equal in size but in opposite directions are called ______________ forces.
Strong
Crazy
Balanced
Unbalanced
The tendency of an object to just keep doing what it is doing.
Laziness
F=MA
No Clue
