Physics Projectile Motion: Horizontal and 2D Concepts and Equations

What is the relationship between X-Axis and Y-Axis velocity in projectile motion?

The X-Axis and Y-Axis velocities act independently from each other.

What is the acceleration due to gravity affecting the Y-Axis motion?

The acceleration is 9.8 m/s² down.

What is the initial vertical velocity (vyi) for horizontal projectile motion?

The initial vertical velocity (vyi) is 0 m/s.

What happens to horizontal velocity (vx) during projectile motion?

Horizontal velocity (vx) is constant throughout the motion.

What is the trajectory of a projectile?

The trajectory is the parabolic path of a projectile.

What is the formula for calculating total velocity in projectile motion?

Total velocity can be calculated using the Pythagorean theorem from the X and Y components.

What is the effect of gravity on the Y-Axis motion of a projectile?

Gravity slows down the projectile on the way up and speeds it up on the way down.

What is the significance of launching a projectile at a 45° angle?

Launching at a 45° angle achieves the furthest downrange distance.

How can you determine the time of flight for a projectile?

Time of flight can be determined using the vertical motion equations.

What is the formula for calculating the horizontal distance traveled by a projectile?

Horizontal distance (x) = horizontal velocity (vx) × time (t).

What is the Y-Axis velocity at the peak of a projectile's flight?

The Y-Axis velocity (vy) is 0 m/s at the peak.

What is the formula for calculating vertical displacement in projectile motion?

Δy = v_yit + ½gt²

In a horizontal projectile problem, what is the value of g?

g is 10 m/s² down.

What is the total velocity of a projectile with vx = 5 m/s and vy = 30 m/s?

Total velocity = √(vx² + vy²) = √(5² + 30²) = 30.4 m/s.

What is the horizontal distance traveled by a baseball thrown at 44 m/s for 18 m?

The horizontal distance is 18 m, as given.

How far does a stone thrown horizontally from a height of 68.4 m land from the base of the cliff?

The distance can be calculated using the time it takes to fall 68.4 m.

What is the Y-component of velocity for a football thrown at an angle of 43°?

The Y-component can be calculated using trigonometric functions based on the angle.

What is the value of horizontal velocity (vx) for a projectile thrown horizontally?

vx remains constant and is equal to the initial horizontal velocity.

What happens to vertical velocity (vy) as a projectile rises?

Vertical velocity (vy) decreases until it reaches 0 m/s at the peak.

What is the formula to find the overall velocity of a projectile?

Overall velocity = √(vx² + vy²).

What is the effect of launching a projectile straight up (90°)?

It gives the largest height but not the furthest distance.
