Projectile Motion - Same Time

The video tutorial discusses an experiment comparing the time it takes for a dropped ball and a horizontally launched ball to hit the ground from the same height. Both balls experience the same acceleration due to gravity and have the same vertical displacement and initial velocity in the Y direction. As a result, they hit the ground simultaneously. The video provides a visual confirmation of this concept, showing both balls at the same height at the same time in slow motion.

What is the main task Mr. P asked the students to perform?

• Calculate the speed of a falling ball.

• Compare the time it takes for two balls to hit the ground.

• Determine the height from which a ball is dropped.

• Measure the distance a ball travels horizontally.

What is the initial vertical velocity of both balls?

• Equal to the speed of sound.

• Ten meters per second.

• Zero.

• Equal to the speed of light.

Why do both balls have the same vertical displacement?

• Because they are launched from different heights.

• Because they have different initial velocities.

• Because they are affected by the same gravitational acceleration.

• Because they are moving in opposite directions.

What is the significance of the uniformly accelerated motion variables being the same for both balls?

• It means they have different times to hit the ground.

• It means they have different vertical displacements.

• It means they have the same time to hit the ground.

• It means they have different horizontal velocities.

What conclusion can be drawn from the visual evidence shown in slow motion?

• Both balls hit the ground at the same time.

• The dropped ball hits the ground first.

• Neither ball hits the ground.

• The horizontally launched ball hits the ground first.
