Friction
Static friction
what is friction on stationary objects?
What can help slow down the speed of the egg drop
what is a parachute?
Net force
What is the sum of all the forces acting on an object?
the equation for Newtons second law
what is F=ma?
Safety features in a car can either stop or decrease the effects of a crash
what is seat-belts and air bags?
Rolling friction
What is friction on rolling objects?
The equation for weight
what is w=ma?
Unbalanced force
what is unequal forces acting against each other?
Newtons first law known as
what is the Law of Inertia?
The logic over forces against objects
What is the more force against an object the faster it will go
Sliding friction
What is friction on objects sliding over a surface?
Some forces act on an object falling through the air are...
what is air resistance and gravity?
Force
what is a push or pull?
Newtons first law states
what is "objects at rest stay at rest unless acted on by an unbalanced force"?
what could potentially happen if you had a faulty seat-belt
what is injury
Fluid friction
what is friction acting on objects going through a fluid?
Air resistance
what is a friction like force that opposes the motion of objects that moves through the air
Define Inertia
what is the tendency of an object to resist a change in motion
the law that states that with every force placed on an object the object exerts an equal and opposite reaction
what is Newtons third law?
Does every object have the same inertia...
what is ,no because inertia is related to the objects mass
What causes friction...
what is when two surfaces touch , they form microwelds, which are the source of friction?
The height we dropped our eggs at
what is 5.54 meters?
Gravity
what is the force of attraction between all objects?
If an object had more mass what would happen to the speed
what is deceleration ?
If you are travelling fast in a car , will you hit another car harder when in a crash
what is yes because the other cars speed will be added to yours
