Why do take derivative?
To find rate of change. Two common examples are: rate of change in position = velocity and rate of change of velocity = acceleration.
How do you safely change a car's velocity?
Slowly press on the accelerator to go more quickly. Slowly press down on the brake pedal to go more slowly. These two operations can safely change a car's velocity.
How do you find acceleration using velocity and time?
Acceleration = (change in velocity) divided by (time for the change)
What does velocity divided by the time interval equal?
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
What is the rate of change of position at a specific point in time?
The rate of change of position is the velocity. The velocity at a specific point in time is called the instantaneous velocity.
What are two of the ways that the velocity of a car can change?
Change in direction change in speed
What two ways can velocity change?
changes in speed or direction or both
Describe the to ways in which velocity can change?
speed and direction
State the ways velocity can change?
the velocity of an object changes when it speeds up or slows down.
In what two ways can velocity be changed?
Velocity changes when the direction of the motion changes.
What is the formula for a change in velocity?
Two ways: If the change in velocity is the result of hitting something, use the Momentum Equation. If the change in velocity is the result of applying a force, use the Impulse Equation. You probably mean this equation, which is: FT = m(Vf - Vo) Or, An object of mass "m" will change from velocity "Vo" to velocity "Vf" if the force "F" is applied for "T" seconds.
What are the two ways in which the acceleration of an object can be increased?
Mass and velocity
What are three ways that an object can change its velocity?

In what ways is a bouncing ball accelerating?
-- On the way down, its speed is increasing, which is a change in velocity, i.e. an acceleration. -- At the bounce, its direction changes, which is a change in velocity, i.e. an acceleration. -- On the way up, its speed is decreasing, which is a change in velocity, i.e. an acceleration.
Why do take derivative?
To find rate of change. Two common examples are: rate of change in position = velocity and rate of change of velocity = acceleration.
What describes velocity?
two things that describe velocity is distance and time.
How do you calculate acceleration if only velocity is given?
Acceleration is a change in velocity over time - (change in velocity) / (time difference). So, you basically need two velocity measurements (or two assumed velocities), and the time difference between the measurements.
