1st Law
The first law states
that an object at rest will remain at rest unless acted on by an outside force and an object in motion will remain in motion unless acted on by outside force
The second law states
an object's mass, force required, and acceleration are all related or proportional to each other.
F =ma
This law states
For every action there is an equal and opposite reaction
A large car will require _________________ force to accelerate.
more
To lift something or go up you must overcome
gravity
A toy race car needs to turn
A force must be applied
I want the soccer ball to accelerate quickly.
I must apply a larger force
A rocket blasts off applying force to the ground and air below
The air and ground below push back allowing the rocket to fly
A race car rolls down a fuzzy ramp and a smooth ramp.
The smooth ramp will allow the car to go faster because of friction
Estuaries are special because
the have salt and fresh water (brackish) home to baby animals, and help decrease flooding and pollution
Brakes apply a ________________ to the wheel to allow the car to ________
force and stop
I need to move a very large boulder in my yard. What will I need to move the boulder?
a lot of force
A balloon is untied and flies across the room
the air blowing out of the balloon pushes on the air behind the balloon that pushes back in an equal and opposite direction.
You kick a soccer ball over smooth dirt and tall grass
The dirt will cause less friction and allow the ball to roll farther.
The prairie biome is (list thing you know about the prairie)
a grassland
temperate
in the US
mostly grass because of low rainfall
If an object needs to turn
A force is required
A small car requires less ______________ to accelerate than a ______________ car.
small large
A reaction pushes _____________
Against or in the opposite direction of the action force
Basketball shoes have grooves or tread on the bottom
to increase friction so basketball players can stop and turn quickly.
The respiratory system
consists of your nose, lungs, bronchi, alveoli, and diaphragm. It helps you breathe.
I want to accelerate the soccer ball so I must
apply a force to the ball
How could I decrease the force needed to move a wagon full of rocks?
Remove some rocks which will decrease mass.
Give an example of the 3rd law of motion
Gravity increases with an objects ___________________ but decreases with an object's distance.
increases
Cold fronts typically produce what kind of weather?
Stormy weather followed by cooler clear weather.
