Physics - Kinematic equations both x + y, Free Fall, and Graphing

Acceleration

The rate of change of velocity

Whats the formula for acceleration?

a = change in velocity / elapsed time

What does kinematic equation 1 tell us?

Kinematic equation 1 tells us how our velocity changes over a given amount of time

What is Kinematic equation 1?

Vf = Vo + at

What is Freefall?

Acceleration due to gravity

What could effect the way an object freefalls

depending on air resistance objects could fall faster or slower

During freefall what is gravity ALWAYS equal to

-9.8 m/s to the power of 2

True or False: It takes the same amount of time for an object to go to its highest than it does for it to fall back down

True

Whats the equation for Average Velocity?

Average Velocity = Vf - Vo / t

What does kinematic equation 2 tell us?

Allows us to determine the position of an object after its accelerated for a given amount of time

What is kinematic equation 2?

Vf = Xo + VoT + ½ at²

What is the purposes of Kinematic equation 3?

It combines both 1 and 2 but takes out time (t)

What are the differences between Position vs Time and Distance vs Time

• position can go backwards

• can be positive or negative

With distance vs time was is the slope equal to?

The slope is speed

With position vs time was is the slope equal to?

The slope is velocity

With velocity vs time was is the slope equal to?

The slope is acceleration

How do you find the displacement in a velocity vs time graph?

by taking the area you can find the displacement, the equation is: delta x = B x H

With a triangle how do you find the displacement?

delta x = ½ BH

BH = vt
