Unit 2 Projectiles Review

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

What is the vertical velocity of a projectile at the apex of its trajectory?

Back

0 m/s

Front

What is the initial vertical speed of a marble rolling off a 1 m high table at 3 m/s?

Back

0 m/s

Front

If two projectiles are fired horizontally with the same velocity from different heights, which one will hit the ground first?

Back

The one on the left.

Front

Does vertical velocity change as a projectile rises and falls?

Back

Yes.

Front

What is the acceleration due to gravity acting on a projectile?

Back

9.8 m/s²

Front

What is the formula to calculate the time of flight for a projectile dropped from a height?

Back

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

Front

What is the horizontal velocity of a projectile if it is fired horizontally?

Back

It remains constant throughout the flight.

Front

What happens to the vertical velocity of a projectile as it ascends?

Back

It decreases until it reaches the apex.

Front

What happens to the vertical velocity of a projectile as it descends?

Back

It increases due to the acceleration of gravity.
