### What is Newton's first law of motion?

An object in motion tends to stay in motion unless acted upon by an outside force. An object at rest tends to stay at rest unless acted upon by an outside force.

### What is Newton's second law of motion?

Force = Mass x Acceleration

### What is Newton's third law of motion?

Every action has an opposite and equal reaction.

A push or a pull

The Newton

### What is the net force of a 20 Newtons west, and 20 Newtons east?

Since the forces are in opposite directions, they subtract. Meaning 20 - 20 = 0 Newtons.

### What is the net force of 10 Newton's west, and 15 Newtons west?

Since the forces are in the same direction they add. Meaning that 10 + 15 Newtons = 25 Newtons west.

### What is the velocity of an object that falls 50 meters in 5 seconds?

Distance/time—or 50/5 --- 10 meters/second.

### What is a pendulum?

And object that swings back and forth with a regular cycle

### What affects that frequency of a pendulum?

The length of the string

### What is the frequency of an object that swings for 10 cycles in 2 seconds?

Frequency = cycle/sec. or 10/2 = 5 (Hertz is the unit)

Ice

The third

### Terminal Velocity = ???

The maximum speed an object can fall in an atmosphere

Archimedes

1
