Free Fall

Front

What is the acceleration of an object in free fall near the Earth's surface?

Back

The acceleration of an object in free fall near the Earth's surface is approximately 10 m/s², directed downward.

Front

What is the formula to calculate the velocity of an object in free fall after a certain time?

Back

The formula is v = g * t, where v is the velocity, g is the acceleration due to gravity (10 m/s²), and t is the time in seconds.

Front

What happens to the velocity of a freely falling object every second?

Back

The velocity of a freely falling object increases by approximately 10 m/s every second.

Front

What is the relationship between time and distance in free fall?

Back

The distance fallen in free fall can be calculated using the formula d = 0.5 * g * t², where d is the distance, g is the acceleration due to gravity, and t is the time.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium (like air) prevents further acceleration.

Front

How does air resistance affect free fall?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration and eventually leading to terminal velocity.

Front

What is the difference between mass and weight in the context of free fall?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass (Weight = mass * g).

Front

What is the significance of Galileo's experiments on free fall?

Back

Galileo demonstrated that in the absence of air resistance, all objects fall at the same rate regardless of their mass.

Front

What is the effect of height on the time it takes for an object to fall?

Back

The time it takes for an object to fall increases with the height from which it is dropped, as it takes longer to cover a greater distance.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.
