What else can I help you with?
Does mass and velocity equal force?
No, mass and velocity do not equal force. Force is the product of mass and acceleration, not velocity. The equation for force is F = ma, where F is the force, m is the mass, and a is the acceleration.
What is the effect of gravity on velocity?
Gravity affects velocity by changing the acceleration of an object. As an object falls, gravity accelerates it, increasing its velocity. Without gravity, an object would move at a constant velocity.
How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]
Why does gravity change velocity?
Gravity changes velocity because it accelerates objects towards the Earth at a rate of 9.81 m/s^2. As objects fall, their velocity increases due to this gravitational acceleration. Conversely, when objects move against gravity, such as when thrown upwards, gravity decreases their velocity until they eventually stop and fall back down.
What causes acceleration to stop at terminal velocity?
Terminal velocity is reached when the force of gravity pulling an object downward is balanced by the force of air resistance pushing back on the object. At this point, the net force on the object is zero, resulting in no further acceleration. This equilibrium leads to a constant velocity where the forces are balanced.
Which word equation is used to calculate the acceleration of a object?
The word equation used to calculate acceleration is: acceleration = change in velocity / time taken. This equation quantifies how an object's velocity changes over a period of time, giving a measure of its rate of acceleration.
How do you find the terminal velocity of an object?
Terminal velocity of an object can be found by balancing the forces acting on it. When the force of gravity pulling the object down is equal to the force of air resistance pushing up, the object reaches its terminal velocity. This can be calculated using the equation: Terminal velocity (mass x acceleration due to gravity) / drag coefficient.
How can the equation force equals mass x acceleration be rewritten?
Equation: Force=Mass X AccelerationIf you are looking for the force, use the equation as is.To find the following, it's assumed that you are given the other two values:Mass= Force / AccelerationAcceleration= Force / MassRemember your labels in your calculations.Mass= force x accelerationForce = mass x accelerationmass = force / accelerationacceleration = force / massSince acceleration = velocity / time we can also substitute velocity / time for acceleration in any of the above.Since velocity = speed / time, we can also substitute speed / time for velocity or speed / (time * time) for acceleration in any of the above.
What word is the definition of the rate velocity changes with time gravity mass velocity or acceleration?
Acceleration is the word that represents the rate at which velocity changes with time. It is a vector quantity that can be caused by factors such as gravity or changes in the mass or velocity of an object.
What is equation for acceleration?
Acceleration = force / mass The correct equation would be acceleration= the final velocity - the initial velocity divided by time which can be written like this: V (Final speed) - U (Starting speed) ____________________________ T (Time)
What is the acceleration of an object that reache terminal velocity?
When an object reaches terminal velocity, its acceleration becomes zero. Terminal velocity occurs when the drag force acting on the object equals the force of gravity pulling it downwards, resulting in no net force and thus no acceleration.
What causes falling objects to reach top velocity?
Falling objects reach top velocity due to the acceleration of gravity pulling them downwards. As the object falls, the force of gravity causes it to accelerate until air resistance (or another opposing force) balances out the acceleration, leading to a constant velocity known as terminal velocity.
