A projectile is any object that is launched into the air and moves under the force of gravity, such as a bullet, rocket, or baseball.
The trajectory of a projectile is affected by the initial velocity, angle of launch, air resistance, and the force of gravity.
The range of a projectile can be calculated using the formula R = (v^2 sin2θ)/g, where R is the range, v is the initial velocity, θ is the angle of launch, and g is the acceleration due to gravity.
Yes, a projectile can change its direction while in motion if it encounters a force that is strong enough to alter its trajectory, such as air resistance or a change in gravity.
The higher the altitude, the less air resistance there is, which can result in a longer range for a projectile. However, the force of gravity also decreases with altitude, so the trajectory may still be affected.
