Vector up equal to the length of a downward vector, and a vector pointing to the left

A box is pushed with a force and accelerated in the negative direction along a surface with no friction , what does the vector diagram look like? (W, Fn, Fa)

Vector up equal to the length of a downward vector, and a vector pointing to the left greater than a vector pointing to the right

A car is pulled and accelerated with a net force of -12 N direction along a surface with friction , what does the vector diagram look like? (W, Fn, Fa, Ff)

1st Law

2 m/s^2

A mass is pulled to the left by a chain with a force of 20 N while a second rope pulls it to the right with a force of 30 N. What is the net acceleration if the mass is 5 Kg?

A vector up and a vector down that are equal in size.

An object is suspended in the air and dangles motionless, due to its weight and the force of tension from a rope. What does the vector diagram look like?

0 N

Car travels with constant speed, it does not speed up or slow down, despite the friction on the road and the force of the engine rotating the tires forward because the Net Force is ...

Second

Newton's _ law explains why: An mass will accelerate in the same direction as its Net Force

First

Newton's _ law explains why: Objects with more mass have a harder time being moved and are more resistance than smaller masses

Third

Newton's _ law is modeled by the following: During an archery contest, an arrow is pushed forward by a bowstring, while the bowstring is pushed backwards by the arrow

4 m/s^2

On Jupiter's moon a Man has a weight of 240 N and a mass of 60 Kg, what is the value of gravity on Jupiter's moon?

Mass

The amount doesn't change, no matter where you go in the universe

Weight

The force of gravity is also known as _

3rd Law

The reason that Normal Force and the Weight of an object will balance each other out when an object is in contact with a surface is because of Newton's ________.

Inertia

The thing all matter has, proportional to its mass; more mass means objects have more _

5 Kg
