Free Fall Motion

Front

What is free fall motion?

Back

Free fall motion is the motion of an object under the influence of gravity only, without any air resistance.

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 9.8 m/s².

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 constant acceleration of gravity.

Front

What is the effect of air resistance on free fall motion?

Back

In free fall motion, air resistance is neglected, meaning the only force acting on the object is gravity.

Front

What is the initial velocity of an object dropped from rest?

Back

The initial velocity of an object dropped from rest is 0 m/s.

Front

How does the acceleration of an object change during free fall?

Back

The acceleration remains constant at 9.8 m/s² throughout the free fall.

Front

What happens to the velocity of a ball thrown upward as it rises?

Back

The velocity of a ball thrown upward decreases as it rises until it reaches its peak.

Front

What happens to the acceleration of a ball thrown upward as it rises?

Back

The acceleration remains constant at -9.8 m/s² (downward) as it rises.

Front

What is the relationship between velocity and acceleration in free fall?

Back

In free fall, the velocity increases while the acceleration remains constant.

Front

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

Back

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