5th Six Weeks Vocabulary Test - Force, Motion, & Energy

Definition: energy of moving electrons or electric charges

• Mechanical Energy

• Chemical Energy

• Electrical Energy

• Nuclear Energy

Definition: the distance between two corresponding parts of a wave (D in image)

• Velocity

• Frequency

• Amplitude

• Wavelength

Answer explanation

The definition refers to the distance between two corresponding parts of a wave, which is known as wavelength. Velocity relates to speed, frequency to cycles per second, and amplitude to wave height, making wavelength the correct choice.

Definition: the maximum distance a wave moves away from the rest position (A in the picture)

• Trough

• Pitch

• Speed

• Amplitude

Answer explanation

Amplitude refers to the maximum distance a wave moves from its rest position, making it the correct answer. Trough, pitch, and speed do not define this specific measurement of wave motion.

Definition: energy locked in the nucleus of an atom

• Electrical Energy

• Nuclear Energy

• Chemical Energy

• Light Energy

Answer explanation

Nuclear energy is the energy stored in the nucleus of an atom. It is released during nuclear reactions, distinguishing it from electrical, chemical, and light energy, which are associated with different processes.

Definition: forces that are intentionally exerted on an object by a person or another object

• Balanced Forces

• Normal Forces

• Unbalanced Forces

• Applied Forces

Answer explanation

Applied forces are the intentional forces exerted on an object by a person or another object, making them the correct choice. Balanced and unbalanced forces refer to the net effect of multiple forces, while normal forces are specific contact forces.

NGSS.3-PS2-1

Definition: the distance a wave travels in one unit of time

• Gravity

• Friction

• Trough

• Speed

Answer explanation

The definition describes how far a wave travels in a given time, which is known as speed. Gravity relates to force, frequency refers to cycles per time, and trough is a wave's lowest point, making speed the correct choice.

NGSS.HS-PS4-1

Definition: the force that pulls objects together

• Friction

• Gravity

• Velocity

• Trough

Answer explanation

Gravity is the force that pulls objects toward each other, such as the Earth pulling us down. Friction is a resistance force, velocity refers to speed, and trough is a term for a low point, making gravity the correct choice.

NGSS.MS-PS2-4

Definition: disturbances that transfer energy from one place to another

• Gravity

• Waves

• Pulses

• Forces

Answer explanation

Waves are disturbances that transfer energy through space or matter, making them the correct choice. Gravity, pulses, and forces do not specifically describe energy transfer in the same way as waves do.

NGSS.MS-PS4-2

Definition: a push or a pull on an object

• Forces

• Accelerations

• Waves

• Masses

Answer explanation

The definition describes a push or pull on an object, which is the definition of forces. Accelerations, waves, and masses do not fit this definition, making 'forces' the correct choice.

NGSS.MS-PS2-2

Definition: the highest part of a transverse wave where the most energy is found (C on the picture)

• Amplitude

• Crest

• Tubercle

• Trough

Answer explanation

The crest is the highest point of a transverse wave, where the energy is maximized. It contrasts with the trough, which is the lowest point. Therefore, the correct answer is crest.
