What are the vertical and horizontal components of a projectile?
The trajectory of a projectile depends on motion in two dimensions. The x component is the horizontal motion of the projectile, and the y component is the vertical motion of the projectile. Once a projectile is in motion, it is in freefall. The only acceleration acting on it is the downward acceleration due to gravity.
What is the magnitude of a projectile motion?
In projectile motion problems, up is defined as the positive direction, so the y component has a magnitude of 49.0 m/s, in the down direction. The magnitude of the velocity is 51.24 m/s. Therefore, the velocity (magnitude and direction) of the ball after 5.00 s was 51.24 m/s, -72.98° down from the horizontal.
Does mass affect a projectile?
Explanation: Mass is not relevant in projectile motion. What is relevant is the initial speed and direction of the object.
Why is acceleration inversely proportional to mass?
As we increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Therefore, mass is inversely proportional to acceleration.
Does light have relativistic mass?
Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely “no”: the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits.
What are the four properties of projectile motion?
Properties of Projectile Motion
- Projectile: An object moving through two dimensions where the only significant force on the object is gravity.
- X: Horizontal position of the projectile.
- Y: Vertical position of the projectile.
- X-Velocity: How quickly the projectile is moving horizontally.
- Y-Velocity: How quickly the projectile is moving vertically.
