acceleration remains the same
at an angle
59 and 61
negative
8X8=64, and 9X9=81; so I would say 8 and 9.
No, it is not irrational because it is a square root of a negative number - which falls into the set of Complex numbers. Irrational numbers can not have an imaginary component.
The acceleration on a projectile as it comes down is approximately equal to the acceleration due to gravity, which is 9.81 m/s^2 on the surface of Earth. This acceleration acts in the downward direction and causes the projectile to increase in velocity as it falls towards the ground.
The curve described by a projectile in flight is called a parabolic trajectory. This curve is a result of the combined effects of the projectile's initial velocity, launch angle, and the force of gravity acting upon it. The projectile follows this path as it moves through the air until it eventually falls to the ground due to gravity.
Rain falls down on crops and dusts falls to the ground.
A projectile that falls around the Earth is in orbit. It is continuously falling towards the Earth due to gravity, but its forward velocity allows it to stay in a curved path around the planet without hitting the ground.
The acceleration is still 9.8 m/s2 but the force applied by gravity is counteracted by the ground.
Yes, when an object falls freely due to gravity, its acceleration is uniform and equal to 9.8 m/s^2, directed towards the center of the Earth. This uniform acceleration is the result of the gravitational force acting on the object and is independent of the object's mass.
Objects accelerate as they fall to the ground due to the force of gravity acting on them. As the object falls, the force of gravity causes it to increase in speed, resulting in acceleration. This acceleration is a result of the unbalanced force acting on the object.
As a rock falls to the ground, its velocity increases due to the acceleration of gravity pulling it downward. Additionally, its kinetic energy increases as its speed and mass contribute to its energy of motion.
Satellites are in constant free-fall. This simply means they are constantly being accelerated by earth's gravity. However, an orbiting satellite's lateral motion is sufficient that the acceleration caused by the earth's gravity causes it to continually circle the earth, instead of crashing to the ground.
-- Gravity causes the vertical component of projectile motion to vary according to the local acceleration of gravity. -- Gravity has no effect at all on the horizontal component of projectile motion.
If gravity is the only force acting on a falling body, then its acceleration is constant until it hits the ground, and the number is 9.81 meters (32.2 feet) per second2 .
The acceleration due to gravity is approximately 9.81 m/s^2 on Earth. When an object falls from a height of 25 m, it will experience this gravitational acceleration as it accelerates towards the ground.
