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 (v_f) - Initial Velocity (v_i)) / Time (t)

Front

What unit is acceleration measured in?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration (deceleration) indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

If an object is at rest, what is its acceleration?

Back

If an object is at rest, its acceleration is 0 m/s².

Front

What is constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time.

Front

How do you determine if an object is speeding up?

Back

An object is speeding up if its velocity is increasing over time.

Front

How do you determine if an object is slowing down?

Back

An object is slowing down if its velocity is decreasing over time.

Front

What is the acceleration of a roller coaster that goes from 6.0 m/s to 70 m/s in 4 seconds?

Back

The acceleration is 16 m/s².
