free fall conceptual physics

Front

What is the acceleration of free-falling objects near the Earth's surface?

Back

Free-falling objects accelerate at 9.8 m/s² due to gravity.

Front

What is the term used to describe the change in velocity over time?

Back

The term is 'acceleration'.

Front

What happens to the acceleration of an object in free fall until it hits the ground?

Back

It accelerates at a constant rate.

Front

How does the velocity of a ball change when it is dropped from a height?

Back

The velocity of the ball increases at a uniform rate.

Front

What is the value of gravitational acceleration in a vacuum near the Earth's surface?

Back

g = 9.8 m/s².

Front

What is the difference between velocity and acceleration?

Back

Velocity is the speed of an object in a given direction, while acceleration is the rate of change of velocity.

Front

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

Back

In a vacuum, the only factor affecting acceleration is gravity, which is constant at 9.8 m/s².

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force.

Front

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

Back

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

Front

What is the significance of free fall in physics?

Back

Free fall demonstrates the effects of gravity on objects and is fundamental in understanding motion.
