Equations
Distance divided by time
What is speed
A moving box experiences this with the ground
What is sliding friction?
This measure of an object is not affected by the gravity of the planet it is on; it tells you how much matter it has
What is mass?
The equal and opposite force to Corbin kicking a soccer ball forward
What is the soccer ball pushing Corbin backward?
The effect on an object's momentum of halving its velocity
What is the velocity is halved?
Final velocity minus initial velocity, divided by time
What is acceleration?
A skateboard on a sidewalk experiences this with the ground
What is rolling friction?
Another word for a particular object's gravitational force
What is weight?
If Net force is doubled, acceleration will do this
What is double?
The object with more momentum between a tennis ball rolling down a ramp and a car at a stop sign
Mass times velocity
What is momentum?
What is fluid friction?
An object only experiencing the force of gravity is said to be in this alliterated term; however there is also usually air resistance
What is free fall?
The book on my table is not accelerating despite gravity pulling it down, thanks to this balancing force
What is normal force?
This says that the total initial momentum of a system is equal to its total final momentum
What is the Law of Conservation of Momentum?
Mass times acceleration
What is Net Force?
Having better tread on your shoes means that you will experience more of this, if you are pushed and do not move
What is static friction
The meaning of g, in Fg=mg
What is acceleration due to gravity?
The reaction force to the Earth pulling Leigha down
What is Leigha pulling the Earth up?
The equation for impulse
What is Δ p=Ft?
Acceleration times time
What is change in velocity?
The direction of the force of friction on a football being punted up and to the left
What is down and to the right?
The two ways to lose weight
What are losing mass and moving to an area of weaker gravity?
The mass of an object if a 50N net force causes it to accelerate at 0.25m/s2
What is 200kg?
The final momentum of a 1,000kg car driving at 3m/s which receives a net force of 200N for 5s
What is 4,000kg*m/s?
