What is projectile motion?

Projectile motion refers to the motion of an object thrown or projected into the air, subject to acceleration due to gravity only.

What variables affect the trajectory of a projectile?

The trajectory of a projectile is affected by initial speed, launch angle, and the acceleration due to gravity.

Define the term 'trajectory.'

Trajectory is the path that a projectile follows through space as a function of time.

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

The launch angle determines the shape and maximum height of the projectile's trajectory.

How does air resistance affect projectile motion?

Air resistance slows down the projectile and can alter its trajectory and range.

State the formula for calculating the range of a projectile.

The range R can be calculated using 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.

What happens to the horizontal component of velocity in projectile motion?

The horizontal component of velocity remains constant if air resistance is negligible.

Explain the vertical component of velocity in projectile motion.

The vertical component of velocity changes due to the acceleration caused by gravity; it decreases on the way up and increases on the way down.

What is the maximum height of a projectile?

The maximum height of a projectile is the highest point it reaches, calculated by (v^2 * sin^2(θ)) / (2g).

How is time of flight calculated for a projectile?

Time of flight for a projectile launched over level ground can be calculated using T = (2v * sin(θ)) / g.

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

In the absence of air resistance, the horizontal acceleration of a projectile is zero.

What effect does an increase in initial speed have on a projectile?

An increase in initial speed increases the range and maximum height of the projectile.

How does gravity affect projectile motion?

Gravity causes the vertical component of velocity to change and determines the parabolic path of the projectile.

What is the optimal launch angle for maximum range on level ground?

The optimal launch angle for maximum range is 45 degrees.

Why can the projectile motion be considered two independent motions?

Projectile motion can be considered as two independent motions: horizontal motion with constant velocity and vertical motion with constant acceleration.
