This vector remains unchanged in the horizontal direction for any projectile.
What is the horizontal velocity of any projectile?
Which direction on a projectile has constant motion?
Horizontal
This is the value for gravitational acceleration on Earth.
What is 9.8m/s^2?
DOUBLE POINTS! A diver running 1.6m/s dives out horizontally from the edge of a vertical cliff and reaches the water 3.0s later. This is the distance away from the cliff they landed.
What is 4.8 m?
If a 100 g object and a 50 g object are dropped from a height of 50 m in a vacuum, which will land first?
Both will land at the same time.
If a projectile is launched horizontally with a velocity of 5 m/s, what is the horizontal velocity right before it hits the ground?
5 m/s (no change)
A tiger leaps horizontally from a 12m high rock with a speed of 4.5 m/s. This is how far from the base of the rock will she land.
What is 7.2 m?
What equation is used to find the height an object is dropped?
y = 1/2at2
DOUBLE POINTS! What is the acceleration of a projectile at the top of the trajectory?
a = 9.8 m/s2
A car traveling at a speed of 50 m/s drives straight off of a cliff. If the cliff is 40 m high, the distance away from the cliff that the car will land is this.
What is 143 meters?
DOUBLE POINTS! This vector becomes increasingly negative as a projectile falls.
Vertical (downward) velocity
At what position is the vertical velocity equal to zero on a projectile?
At the top.
A ball rolls off a table with a speed of 1 m/s and lands 5 meters away from the table. How high was the table?
What is 122.5 meters
This force acts on a projectile
what is gravity
This angle gives you the greatest range in a projectile
What is 45 degrees
