Physics II - Unit 1(Mechanics and Kinematics)

Equation for acceleration

A=f/m or change in velocity/change in time

Equation for distance

distance = speed x time

Equation for speed

speed = distance/time

Equation for time

time = distance/speed or displacement/velocity

Equation for displacement

final position - initial position and velocity x time

Equation for velocity

v=d/t

Force

A push or pull exerted on an object causing a change in velocity, measured in Newtons

Acceleration

The rate at which velocity changes

Equation for Force

F=ma

Equation for mass

m=f/a

Mass

the amount of matter in an object

Matter

anything that takes up space

Distance

The length of a path between two points

Displacement

the change in position of an object, the shortest route

Speed

the rate of change of position - scalar

Velocity

Speed in a given direction - vector

If both velocity and speed are positive or both are negative ____

the object is speeding up

If the velocity and speed are inversed ____

the object is slowing down

What is the acceleration during freefall
