A 20-kg cart travels at 20 m/s in a circle with a radius of 20 m. What is the centripetal force? A turtle takes 3.5 minutes to walk 18 meters towards south along a deserted highway. A truck driver stops and picks up the turtle...
Newton's Second Law also applies in the case of thecentripetal force requirement,which says that if an object is to move in a circle, the net force acting upon it must be inward. Newton's Second Law says that an object being accelerated undergoes a net force, with the direction of the ...
Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
Define uniform circular motion. Define centripetal force and centrifugal force and identify the formula for uniform circular motion. Related to this Question The pilot of a jet plane flying 600 m/s experiences an apparent weig...
A body is able to follow a circular path when a net force called centripetal force is applied on it. A centripetal force has to pull the body inwards ... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question ...
The magnitude at the top of a loop can be calculated using the centripetal force formula: F = mv^2/r, where F is the force, m is the mass of the object, v is the velocity, and r is the radius of the loop. It can also be calculated using the conservation of energy principle...
Torque is the twisting force that tends to cause rotation. It is the measure of how much a force acting on an object causes that object to rotate. Visit to learn how to calculate torque along with its formula, meaning and applications.
An enzyme is a biological catalyst that always a protein. It accelerates the rate in the cell of a particular chemical reaction. The enzyme doesn't destroy during the reaction and may reuse them various times. There are several different types of enzyme molecules in a cell, each unique to ...
The speed limit on some interstate highways is roughly 120 km/h. What is this in meters per second? How to convert kph to mph with a formula A car is traveling at a speed of 8 m/s. It accelerates to a speed of 11 m/s in 7 seconds. Calculate the (a) acceleration of the...
