Describe how electric and magnetic fields are perpendicular in an electromagnetic wave.

They oscillate at right angles to each other.

They are parallel to each other.

They remain stationary in relation to each other.

They move in opposite directions.

These three factors determine how much energy is transferred in a wire.

Frequency, amplitude, and wavelength

Explain what happens at the atomic level when energy is transferred through a wire.

Electrons move and repel each other, transferring energy.

Protons vibrate, releasing heat.

Neutrons flow freely, creating energy.

Atoms split, releasing stored energy.

Explain what happens when energy demand exceeds energy supply.

The grid stores the excess demand.

Energy is pulled from the atmosphere.

The energy supply automatically increases.

Describe how extreme weather affects the infrastructure of the electric grid.

It causes physical damage and increased energy demand.

It makes the grid more efficient.

It reduces energy transfer rates.

Explain how frequency and wavelength are related across the spectrum.

They are inversely proportional (one increases, the other decreases).

They are directly proportional (one increases, the other increases)

They are independent of each other.

They have no consistent relationship.

Explain why gamma rays are more dangerous than radio waves.

Gamma rays have much higher energy and can ionize atoms.

Gamma rays are slower than radio waves.

Gamma rays have lower energy than radio waves.

Gamma rays cannot pass through the human body.

Explain how mass and speed influence stopping distance.

Greater mass and speed increase stopping distance.

Greater mass and speed decrease stopping distance.

Mass has no impact on stopping distance.

Stopping distance is unrelated to speed or mass.

Describe how friction contributes to braking force.

Friction opposes motion and helps stop the vehicle.

Friction increases the stopping distance.

Friction is unrelated to braking force.

Friction makes it harder to stop the vehicle.

If objects with identical mass collide, what can we say about their change in motion?

The objects will experience equal and opposite changes in motion.

Both objects will come to rest after the collision.

The objects will move together at a slower speed after the collision.

The change in motion of each object depends only on their initial velocities.

If objects with different mass collide, what can we say about their change in motion?

The less massive object will experience a larger change in motion.

The more massive object will experience a larger change in motion.

Both objects will experience the same change in motion regardless of mass.

The change in motion for each object depends only on their velocities, not their masses.

Compare the forces two objects exert on each other during a collision.

Both objects exert forces of equal magnitude in opposite directions.

The larger object exerts a greater force.

The smaller object exerts a greater force.

The forces depend on the relative speeds of the objects.

Compare the gravitational force on Earth to that on the Moon for the same object.

The force is the same on both Earth and the Moon.

The force is greater on the Moon.

There is no gravitational force on the Moon.

Describe how mass and distance influence gravitational force in space.

Greater mass and smaller distance increase the force.

Greater mass and smaller distance decrease the force.

Greater mass and distance increase the force.

Mass and distance have no effect on the force.

According to Kepler’s Second Law, objects that orbit the Sun move faster when they are at this point in their orbit.

They always move at a constant speed.

Describe the relationship between orbital speed and distance from the central object.

Speed remains constant regardless of distance.

Speed is independent of distance.

Explain how the speed of an object impacts its interaction with the atmosphere.

Higher speed increases drag and heat.

Speed has no effect on atmospheric interaction.

Speed only affects gravitational pull.
