Projectile motion is caused by the
1. downward force of gravity and horizontal
motion of velocity.
2. downward force of gravity.
3. horizontal motion of velocity.
4. vertical motion of velocity
DOWN
vertical F = - m g where g is acceleration of gravity
so
a = -g
v = Vi - g t
h = Hi + Vi t - (1/2) g t^2
AND
horizontal u = constant all during flight
The correct answer is 1. downward force of gravity and horizontal motion of velocity.
Projectile motion is the motion of an object thrown or launched into the air, under the influence of gravity. It can be seen in various situations such as throwing a ball, shooting a cannonball, or even watching a basketball being thrown into the hoop.
Projectile motion is caused by two main factors: the downward force of gravity and the horizontal motion of velocity.
Gravity pulls objects downwards, causing them to accelerate towards the ground. Regardless of the object's initial velocity or direction, gravity acts vertically, pulling it downward.
On the other hand, the horizontal motion of velocity accounts for the object's movement in the horizontal direction. Even if there is no vertical force acting on the object, it would continue moving horizontally due to the initial velocity it was given.
So, when an object is projected into the air or launched at an angle, it experiences both the downward force of gravity and the ongoing horizontal motion of velocity. These two components combine to create the curved path known as projectile motion.
