What is the equation for uniform circular motion? Uniform circular motion has 2 primary formulas. The first is for centripetal acceleration, which says that a=v^2/r. The second is for centripetal force, which says that Fc=mv^2/r. What is the formula for calculating the centripetal force? For a mass M with tangential speed v at radius R, […]

How much force is needed to accelerate an object of mass 90 kg? Expert-Verified Answer The force needed to accelerate the object 108 N. How much energy does it take to accelerate a 90kg object from rest to 13m s? Final answer: The energy required to accelerate a 90 kg object from rest to 13

What is the formula for total momentum? The total momentum (ptot) of a system is equal to the sum of the momenta of all objects within that system. p t o t = p 1 + p 2 + p 3 + . . . Furthermore, the momentum of each of the individual objects in

Why successful tackle constitutes a perfectly inelastic collision? A successful tackle is a perfectly inelastic collision because of the players involved in the collision stick together and moves with the same velocity after the collision. Some mechanical energy loss occurs in the case of perfectly inelastic collision. What is perfectly inelastic collision in physics? A

What will be the momentum of a body of mass m which is moving with a velocity v? P = M × V. What is the quantity of motion of an object mass in motion or inertia in motion? Momentum can be defined as mass in motion. All objects have mass; so if an object

What is the work done to move a charge in an electric field? The work done moving a charge is given by the distance moved along the direction of the electric field multiplied by the charge and the field strength. In equation form it is W=q∗E∗L where L in this case is the distance along

What will happen to the weight of the child if the lift moves up with constant speed? From the above explanation and given condition when person in an elevator is moving at constant speed in such case the net acceleration will be zero. Thus we can say that person’s weight when he is in a

Is the force that opposes the sliding motion of two surfaces that are touching each other? Friction – a force that opposes motion between two surfaces that are touching. Is the following statement true or false an object that is not accelerating or decelerating has zero net force acting on it? An object that is

Why does a spinning ice skater’s angular velocity increases as she brings her arms in toward her body? When she moves her arms close to her body, she spins faster. Her moment of inertia decreases, so her angular velocity must increase to keep the angular momentum constant. Why is it harder for an ice skater
