Kinematics 2D Vocabulary and Concepts Review

Front

What is the acceleration of a projectile in its vertical motion?

Back

The acceleration of a projectile in its vertical motion is equal to g (approximately 9.81 m/s² downward).

Front

What do we call an object that is launched and is acted upon by gravitational force alone?

Back

An object that is launched and is acted upon by gravitational force alone is called a projectile.

Front

What is the term for the parabolic path of a projectile in motion?

Back

The parabolic path of a projectile motion is called the trajectory.

Front

What is the horizontal velocity of a projectile over time if it is launched with an initial horizontal velocity?

Back

The horizontal velocity of a projectile remains constant over time if air resistance is negligible.

Front

What is the correct graph for the horizontal distance of a projectile launched at a certain angle?

Back

The correct graph for the horizontal distance of a projectile launched at a certain angle is typically a parabolic curve.

Front

Define projectile motion.

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity.

Front

What is the effect of gravity on a projectile's vertical motion?

Back

Gravity causes the vertical motion of a projectile to accelerate downward at a rate of g.

Front

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

Back

As a projectile rises, its vertical velocity decreases until it reaches its peak height.

Front

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

Back

As a projectile falls, its vertical velocity increases due to the acceleration of gravity.

Front

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

Back

Horizontal motion is uniform (constant velocity), while vertical motion is accelerated (due to gravity).
