💥 FORCE & FURY
This law explains why a space probe continues moving at nearly constant speed when no significant unbalanced force acts on it.
Newton’s First Law of Motion — the law of inertia
Wires made of the same material and thickness show decreasing current as their length increases. This property of the wire increases with length and opposes current.
Electrical resistance
Unlike mechanical waves, this type of wave can travel through empty space without needing a material medium.
Electromagnetic wave
This Solar System object is made largely of ice and dust and can develop a coma and tail when it approaches the Sun.
Comet
A car moves around a circular track at constant speed. It is still accelerating because this quantity continuously changes.
Its direction of motion
A power strip becomes unusually warm when several high-power appliances are connected. The safest action is to do this.
Disconnect some appliances and keep the electrical load within the strip’s rated capacity.
Compared with microwaves, ultraviolet radiation has this combination of wavelength and frequency.
Shorter wavelength and higher frequency
This is the bright streak produced when a small piece of space rock enters Earth’s atmosphere.
Meteor
When a swimmer pushes water backward and moves forward, this law explains why the water pushes the swimmer forward with an equal and opposite force.
Newton’s Third Law of Motion - the law of action and reaction
In this type of circuit, each lamp can continue operating even if another lamp fails, and the current divides among the branches.
Parallel circuit
Doctors commonly use this type of electromagnetic radiation to produce images of bones.
X-rays
Ancient meteorites are valuable to scientists because they may preserve information about this event.
The formation of the early Solar System
To investigate how force affects acceleration, a student should keep the mass constant, change this variable, and measure the resulting acceleration.
The applied force
A resistor has the following pattern: 4 V produces 0.20 A, 8 V produces 0.40 A, and 12 V produces 0.60 A. This current should flow at 16 V.
0.80 A
This type of electromagnetic radiation is commonly used by a television remote control to send commands.
Infrared radiation
This instrument separates light into its different wavelengths, allowing astronomers to study an object's chemical composition, temperature, and motion.
spectrometer
A 20-kg cart is pushed with 80 N of force while friction provides 20 N in the opposite direction. This is the cart’s acceleration.
3 m/s²
According to Ohm’s Law, this is the current through a 12-Ω resistor connected to a 24-V battery.
2.0 A
Because excessive exposure to ultraviolet radiation can damage the skin and eyes, scientists should operate UV equipment using these.
Appropriate protective measures
Astronomers use this technology to measure distances and create detailed maps of objects or surfaces by sending out pulses of laser light and measuring the reflected signal.
