Free Fall Acceleration & Gravity

Front

What is acceleration due to gravity?

Back

The acceleration experienced by an object due to gravity.

Front

What is the initial velocity (v_i) of an object dropped from a height?

Back

0 m/s

Front

What is the standard SI unit of acceleration?

Back

m/s²

Front

What is free fall in Newtonian physics?

Back

Any motion of a body where gravity is the only force acting upon it.

Front

What is the standard acceleration due to gravity near the Earth's surface?

Back

9.8 m/s².

Front

How does air resistance affect free fall?

Back

Air resistance opposes the motion of falling objects, affecting their acceleration.

Front

What factors influence the acceleration of an object in free fall?

Back

In a vacuum, the only factor is gravity; in the presence of air, air resistance also plays a role.

Front

What is the formula for calculating the distance fallen in free fall?

Back

d = 0.5 * g * t², where g is the acceleration due to gravity and t is time.

Front

What is the value of g on the Moon compared to Earth?

Back

The acceleration due to gravity on the Moon is about 1.6 m/s², which is less than on Earth.

Front

What is the relationship between mass and weight in the context of gravity?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass * g.
