Answer:
Projectile motion is a type of motion in which an object is launched or thrown into the air and follows a curved path under the influence of gravity. It is characterized by two main components: horizontal motion at a constant velocity (ignoring air resistance) and vertical motion with a constant acceleration due to gravity. These two motions combine to form a parabolic trajectory. Projectile motion is commonly observed in activities like throwing a ball, shooting a cannon, or launching a rocket, and it can be analyzed using principles from physics and mathematics.
Verified answer
Answer:
Projectile motion is the motion of an object that is thrown into the air and only experiences the force of gravity after the initial force that launches it. The object is called a projectile, and its path is called its trajectory.
Examples:
Throwing a ball or a cannonball
The motion of a billiard ball on the billiard table
A motion of a shell fired from a gun
A motion of a boat in a river
The motion of the earth around the sun
Throwing a ball straight upward
Kicking a ball and giving it a speed at an angle to the horizontal
Dropping things and making them free fall
