Acceleration

Front

What is acceleration?

Back

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

Front

Can an object have acceleration if it is slowing down?

Back

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

Front

What is the formula for calculating acceleration?

Back

The formula for acceleration (a) is: a = (final velocity - initial velocity) / time.

Front

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

Back

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

Front

If a car accelerates from 0 to 60 m/s in 5 seconds, what is its acceleration?

Back

The acceleration is 12 m/s².

Front

Does acceleration only occur when an object speeds up?

Back

No, acceleration can occur when an object speeds up, slows down, or changes direction.

Front

What is the difference between positive and negative acceleration?

Back

Positive acceleration occurs when an object speeds up, while negative acceleration (deceleration) occurs when an object slows down.

Front

How does gravity affect acceleration?

Back

Gravity causes objects to accelerate towards the Earth at approximately 9.81 m/s².

Front

What is uniform acceleration?

Back

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

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).
