Projectile Motion: Freefall and 2D GHS

Front

What is 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. It follows a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

The two components are horizontal motion (constant velocity) and vertical motion (accelerated motion due to gravity).

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.8 m/s² downward.

Front

What is the relationship between time of flight for two objects released simultaneously, one dropped and one launched horizontally?

Back

The time of flight is the same for both objects; A = B.

Front

For an object thrown straight up, how does the initial velocity compare to the final velocity at the peak?

Back

The initial velocity is equal to the negative of the final velocity at the peak.

Front

What happens to the range of a horizontally launched projectile if the horizontal velocity increases?

Back

An increase in horizontal velocity (vx) results in a greater range.

Front

What is the optimal angle for maximum range in projectile motion?

Back

The optimal angle for maximum range is 45 degrees.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance decreases the range and alters the trajectory of the projectile.

Front

What is the formula for vertical displacement of an object in free fall?

Back

The formula is d_y = 1/2gt², where g is the acceleration due to gravity.

Front

What is the significance of the two angles of release that add to 90 degrees in projectile motion?

Back

The two angles of release that add to 90 degrees will result in equal horizontal ranges.
