At what point or points of the swing is your kinetic energy the least? Kinetic energy is least at the both at the lowest point and at the top of the swing when you are still for a moment at the highest point just before falling again.

Kinetic energy is least at the top of the swing when you are still for a moment at the highest point just before falling again.

Kinetic energy is least as you are moving from the highest point of the swing moving down to the lowest point of the swing.

Kinetic energy is least at the lowest point at the bottom of the swing.

The correct option is;

Kinetic energy is least as you are moving from he highest point of the swing moving down to the lowest point of the swing

Explanation:

The formula for the kinetic energy, KE, is given by the following formula;

KE = 1/2 × m × v²

Where;

m = The mass of the body in the study

v = The velocity of motion of the body

Therefore, the kinetic energy increases with velocity and therefore, is lowest at the top of the swing when the object is still for a moment

The total mechanical energy of the body is given by the following equation;

Total mechanical energy, = PE + KE = Constant

Where;

PE = The potential energy of the body = Mass × Acceleration due to gravity × Height

Therefore, the potential energy is highest at the top of the motion and lowest at the lowest point, which gives;

The kinetic energy is lowest at the top of the motion and highest at the lowest point of the motion.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
