Whats newtons second law
An object in motion stays in motion unless acted upon by an outside force
What is the definition of Friction?
The force that two surfaces exert on each other when they rub against each other.
What is the equation for momentum?
p=ma
What is the horizontal line?
Runs at 90-degree angle to Earth's gravitational force
What does the first law need?
It needs to have a net force
What affects friction?
The type of surface and how hard the surfaces are pushed together.
What is the momentum variable in an equation?
P
vertical line?
Would run straight down if there was no air resistance, gravity pulls on the object
What is Newtons third law
Every action has an equal and opposite reaction
What are the types of friction?
Static, Kinetic, Rolling, Fluid, and Sliding friction
When will momentum change?
Only if an object is forced to change it motion
What’s an example of horizontal concept?
anything moving forward
What is Newton's First Law also known as?
Law of Inertia
What is Static friction?
Static- between surfaces that are stationary
What is the definition of momentum?
A quantity defined as the product of the mass and velocity of an object
True or False: The two concepts affect each other
false
What is newton's second Law
F=ma
How does fluid friction work?
This occurs when a solid object moves through a fluid. Fluid could be air, water, or materials that flow easily
What is related to momentum?
Force
what is the definition of projectile motion?
the curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth
