This statement is equivalent to saying that neglecting air-resistance, everything accelerates towards the Earth at the same rate. So if you drop any number of objects from a given height, they will all hit the floor at the same time. In other-words, they will all spend the same amount of time in the air (flight time). Now, if you project an object horizontally it will have some horizontal velocity, but that doesn't matter since it is still accelerating towards the Earth at the same rate as if it was dropped. Therefore, the flight time will still be the same as if it were dropped.kylera said:Neglecting air resistance on Earth and regardless of how fast or slow a projectile's initial horizontal velocity is when fired from the same fixed height, they will all fall at the same time. Is this because regardless of the horizontal motions, the vertical motion is the same? Can someone clear this up in more layman-like terms? Much thanks in advance.
Gravity has a significant effect on the trajectory of a projectile. It causes the projectile to follow a curved path, known as a parabola, due to the constant downward force of gravity.
The range of a projectile is influenced by several factors, including the initial velocity, angle of launch, and the effects of air resistance. The force of gravity also plays a role in determining the range of a projectile.
The maximum height a projectile can reach is dependent on the initial velocity and angle of launch. However, it will always be less than the vertical component of the initial velocity.
Air resistance, also known as drag, has a significant impact on the motion of a projectile. It acts in the opposite direction of the projectile's motion, slowing it down and reducing its range.
The trajectory of a projectile will vary depending on the strength of the gravitational force. For example, on Earth, a projectile will follow a parabolic path, but on a planet with a weaker gravitational pull, the trajectory will be less curved.
