Horizontal projectile

Front

What is a horizontal projectile?

Back

A horizontal projectile is an object that is launched horizontally and is subject to gravitational acceleration, resulting in a parabolic trajectory as it falls.

Front

What is the initial vertical velocity of a horizontal projectile at the moment it leaves the launch point?

Back

0 m/s

Front

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

Back

-9.8 m/s² (downward)

Front

What type of motion does a horizontal projectile exhibit in the horizontal direction?

Back

Uniform motion (constant velocity) due to no horizontal acceleration.

Front

What is the formula to calculate the height of a projectile after a certain time in free fall?

Back

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

Front

If a marble rolls off a table at 3 m/s, what is its horizontal velocity just before it hits the ground?

Back

3 m/s (remains constant in horizontal motion).

Front

What does the Velocity-Time graph for horizontal motion look like?

Back

A horizontal line indicating constant velocity.

Front

What is the relationship between time of flight and height for a horizontal projectile?

Back

Time of flight increases with the square root of height.

Front

What is the vertical velocity of a projectile just before it hits the ground?

Back

It increases due to gravitational acceleration, calculated as v = g * t.

Front

How do you determine the range of a horizontal projectile?

Back

Range = horizontal velocity * time of flight.
