Units
The unit for time
What are seconds?
A value for acceleration, represented by the variable “g”, which stays the same on the whole earth
What is 9.81m/s^2?
The equation for velocity, which is dependent on two other variables
What is velocity= (distance)/(time)?
The result of subtracting friction from applied force
What is net force?
The unit for the term that corresponds with the symbol p.
What is (kg • m/s)?
A property of a moving object that remains at a constant amount when in an isolated system
What is momentum?
The equation justified by Newton’s second law
What is F=ma?
The slope of a displacement time graph
What is velocity?
Another representation of the unit “Newton”.
What is a (kg)(m)/(s^2)?
A quantitative property that can neither be created nor destroyed, meaning the total amount always remains the same.
What is energy?
Known as the shortcut equation, this equation for final velocity does not include time
What is (Vf^2)=(Vi^2)+2ad?
The type of friction that is harder to overcome, thus calling for a higher coefficient of friction in comparison with the other type of friction
What is static friction?
2 forms of the same representation of the unit for energy.
What are a joule (J) and (kg)(m^2)/(s^2)?
The value for horizontal acceleration that never changes, due to the fact that gravity only works vertically
What is 0m/s^2?
The equation derived from Hookes Law, which states that the force needed to compress/stretch a string is proportion to the distance it would be stretched
What is Fs=kx?
A vector quantity represented by the area under a velocity-time graph
What is Displacement?
2 forms of the same representation of the unit for power
What are a watt and (kg)(m^2) / (s^3)?
A property of an object that remains the same value, as long as the object is not acted upon by an outside force.
What is the velocity of an object?
The equation for an explosion collision, where the two masses begin together
What is (m1+m2)Vi= (m1)(V1f)+ (m2)(V2f)?
The amount of force exerted on a person as the person pushes a cart with a force of 50N without the cart moving
What is 50N of force?
