Question

Which of these statements is correct about Newton's second law of motion?

It states the meanings of force, mass, and acceleration.

It analyses the meanings of force, mass, and acceleration.

It decribes the relationship between force, mass, and acceleration.

It explains the relationship between force, mass, and acceleration.

Answer 1

Second Law of Motion
II. A force is equal to mass times acceleration: F = ma
This equation shows that gravity, mass, and acceleration are related. The greater the mass of an object, the greater the force necessary to move it. For example, suppose you wanted to push a pencil across a desk with your finger. This would not require too much force. If you applied the same force to a brick, however, the brick would not move. In space, gravity is the universal force that causes objects to accelerate. In space travel, rockets must be able to lift off the ground.

This requires some hefty lift capacities to create enough force to move them upward and away from Earth.
