Free Fall Acceleration

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, typically measured as -9.8 m/s² on Earth.

Front

Do free falling objects move at constant velocity?

Back

No, free falling objects accelerate at -9.8 m/s² due to gravity.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately -9.8 m/s².

Front

What happens to the velocity of a free falling object over time?

Back

The velocity of a free falling object increases over time as it accelerates due to gravity.

Front

If an object is dropped from a height, how does its distance traveled change over time?

Back

The distance traveled increases quadratically over time due to constant acceleration.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

How does weight change on different planets?

Back

Weight changes depending on the gravitational pull of the planet; for example, you weigh more on Earth than on Mars.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × acceleration due to gravity (g).

Front

What would happen to a feather and a metal bolt dropped in a vacuum?

Back

They would hit the ground at the same time because there is no air resistance in a vacuum.

Front

What is the significance of a velocity-time graph for free fall?

Back

A velocity-time graph for free fall shows a straight line with a positive slope, indicating constant acceleration.
