Constant Acceleration Basics

Front

What is a velocity-time graph?

Back

A velocity-time graph is a graphical representation that shows how velocity changes over time.

Front

What is instantaneous acceleration?

Back

Instantaneous acceleration is the change in velocity of an object at a specific instant of time.

Front

What is free fall?

Back

Free fall is the motion of an object falling under the influence of gravity alone, with air resistance ignored.

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 change in velocity at a specific moment.

Front

What happens to the velocity of an object in free fall?

Back

The velocity of an object in free fall increases as it falls due to the acceleration of gravity.

Front

Define acceleration.

Back

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

Front

What is free-fall acceleration?

Back

Free-fall acceleration is the acceleration of an object due to gravity when it is in free fall, approximately 9.81 m/s² on Earth.

Front

How does air resistance affect falling objects?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration compared to free fall.

Front

What is the formula for calculating acceleration?

Back

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

Front

What does a horizontal line on a velocity-time graph indicate?

Back

A horizontal line on a velocity-time graph indicates that the object is moving at a constant velocity.
