What does the impulse momentum theorem state?
Impulse-momentum theorem
What is the theorem that says that impulse that equals Change in momentum?
Impulse-momentum theorem
What could be described as impulse equals change in momentum?
Momentum = Mass x Velocity The change in momentum = (mass of the object x the end velocity) - (mass of the object x the beginning velocity)
Why does an object at a constant speed have no net force?
If speed is constant, acceleration is zero. Anything multiplied by zero equals zero. F = m * a, where F is force, m is mass and a is acceleration. F = m * 0 = 0
What to do if the car change its velocity and the given is the acceleration?
Acceleration equals the change in velocity over a period of time. a= (Vfinal- Vinitial)/t Plug in the acceleration and other information they give you. Then solve.
Average velocity always equals one-half the sum of the initial and final velocities?
Is this a question? or a statement that you are unsure of? Well anyways, this would be correct if acceleration was a constant but if acceleration is not a constant, the (not-constant) acceleration would change the rate of velocity and thus that statement/question would be false.
For motion under central force angular momentum equals?
constant
How do you find the acceleration for a moving object?
Divide the change in position, (total distance covered) by the time it took. Xf = xi +at a = xf-xi / t That is the definition of velocity, not acceleration. Acceleration is rate of change of velocity. (vfinal - vinitial)/t for constant acceleration so vf equals vi + at. Or a equals dV/dt otherwise.
What does the impulse momentum theorem state?
Impulse-momentum theorem
What is the theorem that says that impulse that equals Change in momentum?
Impulse-momentum theorem
What is the de Broglie wave FORMULA?
Wavelength equals Planck's Constant divided by momentum.
Which of Newton's Laws is associated with acceleration equals change in velocity divided by time?
Newton's second law. Actually force, according to him, is defined to be the rate of change of momentum. And as mass is taken as common factor then we have rate of change of velocity which is equated to acceleration. So he derived the famous expression F = m a
What does the law of conversation of momentum mean?
The law of Conservation of Momentum is the result of The Law of Equilibrium, Force equals zero. When Force is zero, Momentum is constant, dP/dt = f = 0. dP/dr = 0 gives P = k a constant.
What is the mass of an object multiplied by its velocity?
The product of mass and velocity of an object is its momentum.
What is the acceleration between t equals 0 and t equals 3?
Acceleration is the rate of change of velocity; without knowing the change in velocity between t=0 and t=3, the acceleration cannot be worked out.
Isaac newton's 3 lost of motion?
1) "Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed on it." 2) "Force is equal to the change in momentum (mV) per change in time. For a constant mass, force equals mass times acceleration." 3) "For every action, there is an equal and opposite re-action." THAT IS ALL!
What is the definition of the second newton law?
Newton's second law of motion: F=ma (force equals mass times acceleration) The rate of change of momentum is proportional to the imposed force and goes in the direction of the force.
