Question

Decide whether these are true or false. Type out the whole sentence in the space and type a "T" beside the letter. Retype the sentences that are not correct. A. An object has acceleration if its velocity is changing. B. Force is measured in joules. C. Gravity is a force.

Answer 1

1. True.

2. False.

3. True.

Step-by-step explanation:

A. True: An object has acceleration if its velocity is changing. In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

B. False: Force is measured in joules. Force is a product of the mass of an object and its rate of acceleration. Thus, force is actually measured in Newton.

C. Gravity is a force. Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
