How much energy does a baseball that weighs 1 point 3 newtons that is thrown so that it attains a velocity of 18 meters per second possess?
Since the ball weighs 1.3 newtons on earth, its mass is (1.3/9.8) kilograms.
When tossed, its kinetic energy is (1/2 m V2) = (0.5 x (1.3/9.8) x 324) = 21.49 joules (rounded)
This number is only valid at the instant the ball leaves the pitcher's hand. It immediately
begins to lose kinetic energy as air resistance slows it down, but it also gains kinetic energy
as gravity accelerates it toward the ground.

When the body will possess non uniform velocity?
The body will possess non uniform velocity when its speed is changing over time, either increasing or decreasing. This can happen when the body is accelerating or decelerating, causing its velocity to be different at different points during its motion.
Can a body possess velocity at the same time in horizontal and vertical direction?
Yes, a body can possess velocity in both horizontal and vertical directions simultaneously. This is known as projectile motion, where an object is moving in a parabolic path due to a combination of horizontal and vertical velocities.
When is a body said to possess kinetic energy?
A body is said to possess kinetic energy when it is in motion. Kinetic energy is the energy an object has due to its motion and is dependent on both its mass and velocity.
What is the diffrance between speed and velocity?
Speed is a scalar quantity that represents how fast an object is moving, while velocity is a vector quantity that includes the speed of the object as well as its direction of motion. Speed tells you how fast something is going, while velocity tells you how fast and in what direction an object is moving.
Why is the body moving with a uniform velocity is zero?
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
When do you use their and they're?
their is to possess something-their baseball, the other is they are-like they are (they're) going to the mall.
What do all objects have in motion?
All objects in motion have a velocity, which is defined as the rate at which an object changes its position. Additionally, they possess kinetic energy, which is the energy associated with their motion.
Can a person moving make kinetic energy?
Yes, when a person is moving, they possess kinetic energy because they have both mass and velocity. This energy is dependent on the person's mass as well as the speed at which they are moving.
What is the future tense of possess?
The future tense of "possess" is "will possess."
Can a body posses two velocities at a specific time?
For different observers (moving at different velocities), the object will have different velocities (relative to the corresponding observer). For one and the same observer, the body will have only one velocity at any given time.
What is the present tense of possess?
Possess is present tense. The past tense is possessed.
Can a body posses velocity when its accleration is zero?
Of course. You need to go back and review the definitions of those terms. Acceleration is the rate at which velocity changes. If velocity is not changing, then there is no acceleration. But the velocity doesn't have to be zero just because it's not changing. Velocity is the speed of an object and the direction in which it's moving. If it's moving at a constant speed in a straight line, then it has plenty of velocity. But since the speed isn't changing and the direction isn't changing, there's no acceleration. If acceleration comes along somehow ... such as by igniting a rocket motor, or gravity pulling the object downward, or someone reaching out and giving the object a push, then the speed or direction may change, and that'll be a change of velocity.
