What is the most commonly used formula to calculate acceleration?
A=Vf-Vi/t Acceleration is the final velocity minus the initial velocity divided by the time it too to reach it
What is the constant used in the formula to find the area of a circle?
You are thinking of pi.A = (pi)r^2
What is formulas finding speed and velocity?
velocity = distance / time There are also some formulae involving acceleration; for example, in the case of constant acceleration: velocity = initial velocity + acceleration x time If the acceleration is not constant, an integral is used instead.
What formula is used to calculate accelation?
Change in velocity / time
What is the meaning of root mean square velocity?
Root mean square velocity is the measure of the velocity of gas particles that is used for solving problems. It is the square root of the average velocity-squared of the molecules in a gas. The formula for root mean square velocity is sqrt(3RT/Mm) where Mm is the molar mass of the gas in kg / mole, R is the gas constant, and T is the temperature in kelvin.
What formula is used to calculate accleration?
Accelaration= change in velocity/time taken OR Acceleration=final velocity- initial velocity/time taken
What is the kinetic energy of a 25-kg toy car traveling at a constant velocity of 2ms?
The formula for kinetic energy is 1/2 x mass x speed squared. Just replace the mass and the velocity with the numbers. Since standard SI units are used, the answer will be in joules.
Is the velocity constant for an object in uniform circular?
Answer: No, the speed is constant, but the velocity changes, since the direction changes. Please be sure you understand the difference between "speed" and "velocity", as used in physics. Speed is scalar which has only magnitude but not direction Whereas velocity is having both. So is a vector quantitiy
What is the formula projectile?
D= vyt+1/2at2 a = (v2-v1)/t These are the two most basic formula that are used to figure out projectile motion questions, combine with SOHCAHTOA (trig) to solve simple projectile motion problems. Remember the horizontal velocity is always constant.
What word is used to show an objects tendency to remain at rest or keep moving with constant velocity?
Inertia
When can the equations of kinematics not be used?
Equations of kinematics or equations of motion can not be used when the body is not accelerating or is moving with a constant velocity.
What is CV type carburetor?
CV stands for (constant velocity). These type carburetors are normally used on motorcycles. A CV carburetor (Constant Velocity) incorporates a vacuum operated slide that varies the venturi size within the carburetor, thus maintaining a constant velocity. The slide also holds a needle that when lifted by the opening slide varies the amount of atomized fuel delivered.
