What is projectile motion?

Back

Projectile motion is the motion of an object that is launched 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 of projectile motion are horizontal motion and vertical motion. The horizontal motion is constant, while the vertical motion is affected by gravity.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its horizontal range and altering its trajectory.

Front

How does the angle of launch affect the range of a projectile?

Back

The optimal angle for maximum range in projectile motion is 45 degrees. Launching at this angle maximizes the horizontal distance traveled.

Front

What is the formula for calculating the time of flight of a projectile?

Back

Time of flight (T) can be calculated using the formula T = (2 * V₀ * sin(θ)) / g, where V₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the horizontal velocity of a projectile?

Back

The horizontal velocity of a projectile remains constant throughout its flight, as there are no horizontal forces acting on it (ignoring air resistance).

Front

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

Back

As a projectile rises, its vertical velocity decreases due to the acceleration of gravity acting downward until it reaches its highest point.

Front

What is the acceleration of a projectile at its highest point?

Back

At the highest point of its trajectory, the vertical velocity is zero, but the acceleration due to gravity remains -9.8 m/s².

Front

How do you calculate the maximum height of a projectile?

Back

Maximum height (H) can be calculated using the formula H = (V₀² * sin²(θ)) / (2 * g), where V₀ is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.

Front

What is the relationship between the horizontal and vertical components of a projectile's motion?

Back

The horizontal and vertical components of a projectile's motion are independent of each other; the horizontal component remains constant while the vertical component changes due to gravity.
