How do you find instantaneous velocity from a position function?

Take the derivative of the position function with respect to time: v(t)=dx(t)dtv(t) = \frac{dx(t)}{dt}.

How do you find instantaneous acceleration from a velocity function?

Take the derivative of the velocity function with respect to time: a(t)=dv(t)dta(t) = \frac{dv(t)}{dt}.

How do you find displacement from a velocity function?

Integrate the velocity function with respect to time over the desired time interval: Δx=t1t2v(t)dt\Delta x = \int_{t_1}^{t_2} v(t) dt.

How do you find velocity from an acceleration function?

Integrate the acceleration function with respect to time over the desired time interval: Δv=t1t2a(t)dt\Delta v = \int_{t_1}^{t_2} a(t) dt.

What is the process for simplifying objects in kinematics?

Model objects as point particles, ignoring size and shape, and focusing on mass and charge.

What is the difference between average and instantaneous velocity?

Average velocity: Velocity over a time interval. | Instantaneous velocity: Velocity at a specific moment.

How do average and instantaneous values relate as the time interval approaches zero?

As the time interval approaches zero, average values converge to instantaneous values.

Differentiate between distance and displacement.

Distance: Total path length traveled. | Displacement: Change in position from start to finish.

Compare and contrast velocity and acceleration.

Velocity: Rate of change of displacement (speed with direction). | Acceleration: Rate of change of velocity.

What's the difference between constant velocity and no velocity?

Constant Velocity: Object is moving at a steady rate in a straight line. | No Velocity: Object is at rest.

What is displacement?

The change in an object's position, calculated as final position minus initial position: Δx=xx0\Delta x = x - x_{0}

Define average velocity.

The rate of change of displacement over a time interval: vavg=ΔxΔtv_{avg} = \frac{\Delta x}{\Delta t}

What is average acceleration?

The rate of change of velocity over a time interval: aavg=ΔvΔta_{avg} = \frac{\Delta v}{\Delta t}

Define instantaneous velocity.

The velocity of an object at a specific moment in time. It is the average velocity over an infinitesimally small time interval.

What is meant by 'object model simplification'?

Treating objects as points, ignoring size, shape, and internal configuration for simplified analysis.
