FIZIX1st Sem Review - Projectiles

Front

What is the time it takes for a projectile to hit the ground when fired horizontally from a height of 5.0 m?

Back

1.0 s

Front

If an object is projected horizontally from a cliff, how does the time to hit the ground compare to an object that is simply dropped?

Back

The same amount of time as if it was just dropped.

Front

In projectile motion, what force acts in the vertical direction causing the object to follow a parabolic path?

Back

Gravity

Front

What is the vertical displacement in a projectile motion diagram?

Back

It is represented by the letter A.

Front

If two objects are projected horizontally from the same height, will they hit the ground at the same time regardless of their horizontal speeds?

Back

Yes, both will hit the ground at the same time.

Front

Define projectile motion.

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following a curved path.

Front

What are the two components of projectile motion?

Back

Horizontal and vertical components.

Front

How does air resistance affect projectile motion?

Back

Air resistance opposes the motion, reducing the range and altering the trajectory.

Front

What is the formula to calculate the time of flight for a projectile launched horizontally?

Back

t = √(2h/g), where h is the height and g is the acceleration due to gravity.

Front

What is the horizontal velocity of a projectile?

Back

It remains constant throughout the motion.
