Acceleration

Front

What is acceleration?

Back

A change in motion.

Front

How is acceleration defined mathematically?

Back

Acceleration is defined as the change in velocity divided by the time interval.

Front

What is the formula for average acceleration?

Back

(final velocity - initial velocity) ÷ time.

Front

If a golf ball rolls up a hill and slows down at a constant rate, what happens to its velocity?

Back

Its velocity decreases over time.

Front

What happens to a car's acceleration when it rounds a corner at a constant speed?

Back

Its direction changes, resulting in acceleration.

Front

What is the unit of acceleration in the SI system?

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 an object has a constant acceleration, what can be said about its velocity?

Back

Its velocity changes at a constant rate.

Front

What is the relationship between acceleration and force according to Newton's second law?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass (F = ma).

Front

How does friction affect acceleration?

Back

Friction opposes motion, which can decrease acceleration.
