This quiz is designed to test your knowledge of the terms from Week One of the Roller Coaster Unit.

• 1.

### An incline or angle in reference to a vertical or horizontal plane is called

• A.

Friction

• B.

Speed

• C.

Slope

• D.

Velocity

C. Slope
Explanation
The correct answer is "Slope". A slope refers to an incline or angle in reference to a vertical or horizontal plane. It is commonly used to describe the steepness or gradient of a surface or terrain. The term "slope" is often used in mathematics, engineering, and physics to quantify the degree of inclination or decline.

### The speed of something in a given direction is called

• A.

Acceleration

• B.

Velocity

• C.

Speed

• D.

Gravity

B. Velocity
Explanation
Velocity is the correct answer because it refers to the speed of something in a given direction. While speed only indicates how fast something is moving, velocity includes both the speed and direction of an object. Acceleration refers to the rate at which an object's velocity changes over time, and gravity is a force that attracts objects towards each other.

### The increase in the rate or speed of something is called

• A.

Acceleration

• B.

Kinetic Energy

• C.

Potential Energy

• D.

Speed

A. Acceleration
Explanation
Acceleration is the correct answer because it refers to the increase in the rate or speed of something. It is a measure of how quickly an object's velocity changes over time. When an object speeds up, slows down, or changes direction, it is experiencing acceleration. Therefore, acceleration is the appropriate term to describe the increase in the rate or speed of something.

Rate this question:

• 4.

### Energy of motion is called _______ energy.

kinetic
Explanation
Kinetic energy refers to the energy possessed by an object due to its motion. It is the energy that an object possesses when it is in motion and is directly proportional to its mass and the square of its velocity. Therefore, the correct answer is "kinetic" energy.

Rate this question:

• 5.

### Stored energy due to object's position is called _________ energy.

potential
Explanation
Potential energy is the stored energy that an object possesses due to its position or state. It is the energy that can be converted into other forms of energy, such as kinetic energy, when the object is in motion. Potential energy can exist in various forms, such as gravitational potential energy, elastic potential energy, and chemical potential energy.
