What is the graph of the motion of a body falling vertically that reaches a terminal speed?
The graph of the motion of a body falling vertically that reaches a terminal speed would show an initial acceleration until the body reaches its terminal velocity. At this point, the graph would level off, showing constant velocity as the body falls continuously.
When an object reaches terminal velocity what is the net force acting on the object?
When an object is at terminal velocity, the two forces due to gravity and drag are equal, so the object ceases accelerating. Its motion is constant and vertically downward.
What is A football kicked off at an angle 20 from the ground reaches a maximum height of 4.7 m What is the initial velocity of the kick?
To find the initial velocity of the kick, you can use the equation for projectile motion. The maximum height reached by the football is related to the initial vertical velocity component. By using trigonometric functions, you can determine the initial vertical velocity component and then calculate the initial velocity of the kick.
When you drop a penny what kind of motion does it have?
When you drop a penny, it undergoes free fall motion, accelerating due to gravity until it reaches terminal velocity. There is no horizontal motion involved, and the speed of the penny increases as it falls.
What is air resistance and terminal velocity?
Air resistance is the force that opposes the motion of an object moving through the air. Terminal velocity is the maximum constant speed a falling object reaches when the force of gravity is balanced by the force of air resistance, resulting in no acceleration.
The greatest velocity a falling object reaches?
The greatest velocity that a falling object can achieve is termed, terminal velocity. The equation for terminal velocity is equal to the square root of (2mg / (air density * projected area * drag coefficient))
When the initial velocity is zero?
When the initial velocity is zero, the object is at rest, and there is no motion in the direction of the velocity. This means that the object will not have any kinetic energy due to its velocity at the initial moment.
What is the initial velocity of a bullet fired verticaly upward from a gun and reaches a height of 7000 ft?
The initial velocity of the bullet can be obtained by using the kinematic equation for projectile motion. Assuming we neglect air resistance, the initial velocity of the bullet fired vertically upward from a gun can be calculated by setting the final velocity as 0 when it reaches the maximum height of 7000 ft. Using the equation v^2 = u^2 + 2as, where v is the final velocity (0 m/s), u is the initial velocity, a is the acceleration due to gravity, and s is the total displacement. Solve for u to find the initial velocity of the bullet.
What is terminal motion?
Terminal motion typically refers to the final stage of an object's movement when it reaches a constant velocity or stops moving altogether due to the forces acting upon it. This can occur when an object reaches its maximum speed or when opposing forces come into equilibrium.
How to find the initial velocity of an object in motion?
To find the initial velocity of an object in motion, you can use the equation: initial velocity final velocity - (acceleration x time). This equation helps you calculate the starting speed of the object based on its final velocity, acceleration, and the time it took to reach that final velocity.
initial velocity what bis this?
Initial velocity is the velocity of an object at the starting point of its motion. It refers to the speed and direction of an object at the beginning of its journey.
What does initial velocity means?
Initial velocity refers to the velocity of an object at the very beginning of its motion or in a particular interval of time. It is typically denoted as "u" in physics equations and is crucial for determining the subsequent motion and trajectory of the object. Initial velocity is an important parameter in analyzing various phenomena such as projectile motion, collisions, and more.
