Acceleration Flashcard Practice

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time.

Front

How is acceleration calculated?

Back

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

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If a roller coaster accelerates from 6.0 m/s to 70 m/s in 4 seconds, what is the acceleration?

Back

16 m/s².

Front

A golf ball accelerates at 15 m/s² from 0 m/s to 50 m/s. How long does it take to accelerate?

Back

3.3 seconds.

Front

What does it mean if an object has a negative acceleration?

Back

Negative acceleration indicates that the object is slowing down.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating the change in velocity?

Back

Change in velocity = final velocity - initial velocity.

Front

What is the relationship between acceleration and force?

Back

According to Newton's second law, acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass (F = ma).

Front

What is uniform acceleration?

Back

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