2D Kinematics

Front

What is the horizontal component of a projectile's acceleration in general projectile motion with no air resistance?

Back

is always zero.

Front

What is a quantity that has both magnitude and direction called?

Back

vector quantity.

Front

What shape does a projectile make during its motion?

Back

Parabola.

Front

What happens to the velocity of a ball as it is dropped off a cliff?

Back

It increases at a uniform rate.

Front

How does a ball projected horizontally from a cliff move?

Back

The ball moves horizontally with a constant velocity but accelerates downward.

Front

What is the definition of a scalar quantity?

Back

A quantity that has only magnitude and no direction.

Front

What is the acceleration due to gravity near the Earth's surface?

Back

Approximately 9.8 m/s².

Front

What is the formula for calculating the range of a projectile?

Back

Range = (initial velocity² * sin(2θ)) / g, where θ is the launch angle and g is the acceleration due to gravity.

Front

What is the difference between vertical and horizontal motion in projectile motion?

Back

Vertical motion is influenced by gravity, while horizontal motion is constant and not influenced by gravity.

Front

What is the term for the highest point in the trajectory of a projectile?

Back

Apex.
