Which of the following is a scalar? centripetal force weight speed acceleration

A scalar is one of the two types of measurements for scientists. The physical quantities they need to measure are classified into two categories: Scalars and vectors. Scalar quantities just have magnitude or size. Some examples of scalar quantities are temperature, mass (weight), energy for example joules, distance, speed for example meters per second and density for example kilograms per meter cubed.

Explanation:

A scalar is a measurement of quantity; it fully describes the magnitude and it is represented by a single number, some examples of scalar quantities are speed, volume, mass, temperature, power, energy and time.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
