Answer: What is the acceleration of an object that moves at constant velocity? Acceleration is Zero
What is the net force on the object in this case? The ner force is also Zero
Explanation: If the velocity is constant means that the acceleration is zero, from Newton second law is clear that net force is also zero
Fnet= m* a as v is constant a=0 this Fnet is zero.
A electron has a negative charge. They represent energy levels.
An example of the use of an electron is the spherical shell. The larger the shell, the more energy the electron has.
Resultant: in biomechanics, often resultant vectors are calculated, in which case a single vector is formed by combining (or summing) two or more other vectors. For example, combining horizontal and vertical forces into a resultant force.
Answer:
c. The truck with greater speed
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents speed or velocity measured in metres per seconds square.
From the above formula, we can deduce that the kinetic energy of an object is directly proportional to the square of the value of its velocity or speed.
Hence, the truck with greater speed would have a greater amount of kinetic energy.
