Projectile Motion

Front

What are the two components of projectile motion?

Back

The two components of projectile motion are horizontal (x) and vertical (y) components.

Front

How does the initial horizontal velocity of a projectile compare to its final horizontal velocity?

Back

The initial horizontal velocity of a projectile is equal to its final horizontal velocity.

Front

At the highest point of a projectile's path, how does its speed compare to the speeds at points of equal height?

Back

At the highest point (Q), the speed is less than at points P and R, which are at the same height (v_Q < v_R = v_P).

Front

What shape does the path of a projectile follow?

Back

The path of a projectile follows a parabolic shape.

Front

What is the speed of an object in free fall after 2 seconds?

Back

The speed of an object in free fall after 2 seconds is 19.6 m/s.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance can affect the trajectory and speed of a projectile, but in ideal conditions (negligible air friction), it does not alter the parabolic path.

Front

What is the acceleration of a projectile in the vertical direction?

Back

The acceleration of a projectile in the vertical direction is due to gravity, approximately 9.8 m/s² downward.

Front

How does the horizontal motion of a projectile differ from its vertical motion?

Back

The horizontal motion of a projectile is uniform (constant velocity), while the vertical motion is accelerated (due to gravity).

Front

What factors affect the range of a projectile?

Back

The range of a projectile is affected by its initial velocity, launch angle, and the height from which it is launched.

Front

What is the launch angle that maximizes the range of a projectile?

Back

The launch angle that maximizes the range of a projectile is 45 degrees.
