Projectile Motion Test

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 time of flight of a projectile?

Back

The time of flight of a projectile is affected by its initial velocity, launch angle, and the acceleration due to gravity.

Front

How does launch angle affect the range of a projectile?

Back

The launch angle determines the trajectory of the projectile. A launch angle of 45 degrees typically provides the maximum range in a vacuum.

Front

What is the independence of motion in projectile motion?

Back

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

Front

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

Back

The horizontal range R of a projectile is given by the formula R = (v^2 * sin(2θ)) / g, where v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the maximum height of a projectile?

Back

The maximum height H of a projectile can be calculated using the formula H = (v^2 * sin^2(θ)) / (2g), where v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What happens to the vertical velocity of a projectile at its peak height?

Back

At the peak height of a projectile's trajectory, the vertical velocity is zero.

Front

How does air resistance affect projectile motion?

Back

Air resistance opposes the motion of a projectile, reducing its range and altering its trajectory compared to ideal projectile motion without air resistance.

Front

What is the effect of increasing the initial velocity on the range of a projectile?

Back

Increasing the initial velocity of a projectile increases its range, assuming the launch angle remains constant.

Front

What is the relationship between the time of flight and the launch angle?

Back

For a given initial velocity, the time of flight increases with the launch angle up to 90 degrees, after which it decreases.
