Acceleration

Front

What is the formula for calculating average acceleration?

Back

Average acceleration = (final velocity - initial velocity) ÷ time

Front

If a golf ball starts with a speed of 2 m/s and slows at a rate of 0.5 m/s², what is its velocity after 2 seconds?

Back

1 m/s

Front

How do you calculate acceleration when given initial and final velocities and time?

Back

Acceleration = (final velocity - initial velocity) ÷ time

Front

True or False: Acceleration only occurs when an object speeds up.

Back

False

Front

What is acceleration?

Back

A change in motion.

Front

What are the units of acceleration?

Back

Meters per second squared (m/s²).

Front

What does a negative acceleration indicate?

Back

It indicates that an object is slowing down.

Front

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

Back

Acceleration = (50 m/s - 20 m/s) ÷ 5 s = 6 m/s².

Front

What is the difference between average acceleration and instantaneous acceleration?

Back

Average acceleration is the change in velocity over a time interval, while instantaneous acceleration is the acceleration at a specific moment in time.

Front

What is the effect of constant acceleration on an object's velocity?

Back

The object's velocity changes at a constant rate.
