Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (Vf) - Initial Velocity (Vi)) / Time (t)

Front

If a car accelerates from 0 to 20 m/s in 3.5 seconds, what is its acceleration?

Back

5.7 m/s²

Front

What is the unit of measurement for acceleration in the metric system?

Back

m/s²

Front

Can an object have acceleration if it is slowing down?

Back

Yes, an object can have acceleration even when it is slowing down; this is called negative acceleration or deceleration.

Front

What does a negative acceleration value indicate?

Back

A negative acceleration value indicates that an object is slowing down.

Front

What is the relationship between acceleration and velocity?

Back

Acceleration is the change in velocity over time; it can increase or decrease the speed of an object.

Front

What equation relates initial velocity, final velocity, acceleration, and time?

Back

Vf = Vi + (a * t)

Front

How do you determine the time it takes for an object to stop given its initial velocity and acceleration?

Back

Use the equation: t = (Vf - Vi) / a, where Vf is 0 for stopping.

Front

What is the significance of the time interval in the calculation of acceleration?

Back

The time interval is crucial as it determines how quickly the change in velocity occurs.
