Freefall

Front

What is free fall?

Back

Free fall is the motion of an object where the only force acting on it is gravity.

Front

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

Back

The acceleration is approximately -9.8 m/s².

Front

Do objects of different masses fall at the same rate in a vacuum?

Back

Yes, they fall with equal accelerations regardless of their masses.

Front

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

Back

The velocity increases at a uniform rate.

Front

What is the term for the force that opposes the motion of an object through the air?

Back

Air resistance.

Front

If a ball is thrown upwards and caught at the same height, what can be said about its speed when caught?

Back

The speed will be the same as when it was thrown upwards, assuming no air resistance.

Front

What is the effect of air resistance on free falling objects?

Back

Air resistance slows down the acceleration of falling objects.

Front

What is the difference between free fall and projectile motion?

Back

Free fall is only influenced by gravity, while projectile motion is influenced by both gravity and initial velocity.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

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

Back

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