5 Questions
What is projectile motion?
Projectile motion is the motion of a body thrown with some initial velocity at an angle with the horizontal direction and allowed to move in two dimensions under the action of gravity alone.
What is the trajectory of a projectile?
The path that the object follows is called its trajectory.
When does projectile motion occur?
Projectile motion only occurs when there is one force applied at the beginning on the trajectory, after which the only interference is from gravity.
What is the principle of physical independence of motions in projectile motion?
The principle states that the horizontal motion and vertical motion of a projectile take place independent of each other.
Give examples of projectile motion.
Examples of projectile motion include a bomb released from an aeroplane, a bullet fired from a gun, an arrow released from a bow, and a piece of stone thrown in any direction.
Study Notes
Projectile Motion
- Projectile motion is a type of motion that occurs when a body is thrown with some initial velocity at an angle with the horizontal direction, and then allowed to move in two dimensions under the action of gravity alone.
- The path followed by the object is called its trajectory.
Characteristics of Projectile Motion
- Projectile motion only occurs when there is one force applied at the beginning of the trajectory, after which the only interference is from gravity.
Examples of Projectile Motion
- A bomb released from an aeroplane in level flight
- A bullet fired from a gun
- An arrow released from a bow
- A piece of stone thrown in any direction
Key Features of Projectile Motion
- Projectile motion is a two-dimensional motion.
- It can be discussed in two parts: horizontal motion and vertical motion.
- These two motions take place independent of each other, which is called the principle of physical independence of motions.
