Freefall & Horizontal Launch, Projectile Launch and the Range Formula

Question 1

What is Newton’s first law?

Answer 1

It is also known as the Law of Inertia, which states that an object with mass will continue what it is doing until a force acts upon it.

Question 2

A force is a…

Answer 2

a push, a pull and a vector.

Question 3

What is Newton’s second law?

Answer 3

It states that an object that is subjected to a force will accelerate according to the strength of the force and mass of the object. It is described in a formula: F=m*a.

Question 4

Falling objects accelerate downwards because…

Answer 4

of the force of gravity. Gravity is a force of attraction between every pair of massive objects. Earth’s gravity is -9.8 m/s2.

Question 5

What is Newton’s third law?

Answer 5

For every force, there is an equal and opposite force.

Question 6

Horizontal launch is a combination of…

Answer 6

2 types of motion. The horizontal motion is unaffected by gravity, so it is uniform (URM). The vertical motion is accelerated by gravity (UARM).
