1D Kinematics

Definitions

1

A quantity that is defined by magnitude only

What is a scalar?

2

A quantity that is defined by Magnitude and Direction

What is a vector?

3

Vector quantity that refers to the straight line distance of an object's path from start to finish

What is displacement?

4

An object that is being accelerated only by gravity is in this state of motion

What is free fall?

5

Designated by a positive or negative sign on a vector quantity

What is direction?

Speed

1

Speed equals this over time.

Distance.

2

Speed is the size of the ___ travelled.

Path.

3

If your distance and displacement are equal, your speed and velocity are this

Equal

4

These are the two different types of speed that we have mentioned.

Instantaneous and average speed.

5

When solving for speed, s = d/t. When finding distance, d = this

d = s * t

Motion

1

This is the displacement of a man who walks 50m north, and then turns around and walks 30m south

What is 20m north?

2

This is the average speed of a man who walks 50m in 10s

What is 5m/s?

3

This is the acceleration of a car that accelerates from 40m/s to 50m/s in 5 seconds

What is 2 m/s^2?

4

The displacement of a person who walks 30m North, and then 40m West.

50m Northwest.

5

The displacement of a racer between the start and the end of a race.

Zero.

Acceleration

1

The symbol we use to represent change

What is delta or 

\Delta

2

We accelerate when we change our velocity. So we can accelerate by speeding up, slowing down, or doing this. 

Changing direction.

3

We have negative acceleration when doing this.

Slowing down.

4

When your velocity is constant, your acceleration is this.

Zero.

5

This is the acceleration of an object that reaches 98m/s after falling for 10 seconds.

9.8m/s²

General physics

1

Kinematics is the study of this

Motion/movement.

2

When a person touches everyday objects, this fundamental force is in action.

Electromagnetism.

3

Erwin Schrodinger proposed a famous thought expirment called this

Schrodinger's Cat

4

Physics covers the biggest to the smallest of interactions. This fundamental force deals with the biggest (i.e., planets, stars, black holes...).

Gravity

5

These are the 4 fundamental forces in physics

Gravitation

Electromagnetic

Strong Nuclear Force

Weak Nuclear Force
