Front

How is acceleration calculated?

Back

Acceleration is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

What units are commonly used to measure acceleration?

Back

Common units for acceleration include meters per second squared (m/s²).

Front

If a car's velocity increases from 20 m/s to 50 m/s in 5 seconds, what is its acceleration?

Back

The acceleration is 6 m/s².

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 does a position vs. time graph indicate about an object's motion?

Back

A position vs. time graph shows how the position of an object changes over time, indicating whether it is accelerating or moving at a constant speed.

Front

What is the formula for calculating acceleration when given initial and final velocities and time?

Back

The formula is a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.

How does acceleration affect the motion of a plane during landing?

Back

During landing, a plane experiences negative acceleration as it slows down from its landing speed.
