The formula for the energy of motion is: KE=0.5\times m\times v^2 where KE is kinetic energy in joules, m is mass in kilograms and v is velocity in meters per second. Force and Work Newton's three laws of motion form the basis for classical physics. The first law defines force as...
1.If the coefficient of kinetic friction between a 28 kg crate and the floor is 0.25,what horizontal force (in N) is required to move the crate at a constant speed across the floor?2.A person has a reasonable chance of surviving an automobile crash if the deceleration is no more than ...
What is the formula for mass and weight? The formula for weight states that weight is equal to mass multiplied by the acceleration of gravity (i.e., W=MG). The formula for mass can therefore be M=W/G. However, mass is also equal to the net force needed to accelerate an object, ...
What is the formula for torque? What is mean by torque? Define torque. What are the units of torque? What is the SI unit for torque? Give a definition of the following term: Torque. Explain and exemplify the concept of torque.
What is the formula of density of a nucleus What is the formula of radius of a nucleus? What is the value of Atomic mass unit (a.m.u.)? What is the value of electron volt (eV) and milli-electron volt (MeV)? What is the formula for Bragg’s law? What is...
For ordinary matter, momentum is given by the formulaP = mv, wherePis momentum,mis mass, andvis velocity. Even tiny amounts of matter can have vast amounts of momentum if the matter is moving fast enough. For example, in 1991, an ultra-high-energy cosmic ray, now known as the OMG ...
What is the unit for potential difference? What is the difference between viscosity and friction? What does the shape of a distance vs. time graph indicate? How does an object's speed affect its aerodynamics? What is the difference between gravitational potential energy and elastic poten...
Sub-question 1: How does the Huskylens work and why did we use it? The Huskylens is a piece of hardware made by DFRobot. The Huskylens has different functions and can be used for different purposes.[1] What is the Huskylens able to do?
A block with mass of 500kg is being pulled by a cable that is set an angle of 12 degrees above the horizontal.If the coefficient of static friction is 1.42 and the coefficient of kinetic friction is 0.76,what is the tension in the cable just before the block starts moving and what is...
brake pedal until the vehicle comes to a complete stop. This distance is the sum of several distances that the car travels while the driver makes a decision, the brakes are activated and the vehicle slows down until it stops. The stopping distancesstopis determined using the followin...
