Projectile Motion Review

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 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 optimal angle for maximum range in projectile motion?

Back

The optimal angle for maximum range in projectile motion, in the absence of air resistance, is 45 degrees.

Front

How does height affect the time of flight of a projectile?

Back

The time of flight increases with height; a projectile launched from a greater height will take longer to hit the ground.

Front

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

Back

Horizontal and vertical motions are independent of each other. The horizontal motion is uniform, while the vertical motion is influenced by gravity.

Front

What happens to the horizontal velocity of a projectile as it moves through the air?

Back

In the absence of air resistance, the horizontal velocity of a projectile remains constant throughout its flight.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance decreases the range and alters the trajectory of a projectile, causing it to fall short of its expected landing point.

Front

If two projectiles are launched at the same angle but different speeds, which will have a greater range?

Back

The projectile launched at the higher speed will have a greater range.

Front

What is the formula for the range of a projectile launched at an angle?

Back

The range R of a projectile launched at an angle θ with initial velocity v is given by R = (v² * sin(2θ)) / g, where g is the acceleration due to gravity.

Front

What is the significance of the launch angle in projectile motion?

Back

The launch angle determines the shape of the trajectory and affects both the maximum height and the range of the projectile.
