Projectile Motion

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 of projectile motion are horizontal motion (constant velocity) and vertical motion (accelerated motion due to gravity).

Front

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

Back

The acceleration of a projectile in the vertical direction is approximately -9.81 m/s², directed downward due to gravity.

Front

At what point is the vertical velocity (Vy) of a projectile zero?

Back

The vertical velocity (Vy) of a projectile is zero at the peak of its trajectory.

Front

What is the horizontal velocity (Vx) of a projectile?

Back

The horizontal velocity (Vx) of a projectile remains constant throughout its flight, assuming no air resistance.

Front

What is the formula for the range of a projectile?

Back

The range (R) of a projectile is given by the formula R = (V₀² * sin(2θ)) / g, where V₀ is the initial velocity, θ is the launch angle, and 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 the range and maximum height of the projectile.

Front

What is the maximum height of a projectile?

Back

The maximum height (H) of a projectile can be calculated using the formula H = (V₀² * sin²(θ)) / (2g).

Front

What is the resultant velocity of a projectile?

Back

The resultant velocity (Vo) of a projectile is the vector sum of its horizontal (Vx) and vertical (Vy) components.

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.
