Physical Science Milestones Review #2

Front

What is diffraction?

Back

Diffraction is the bending of light waves as they pass through openings in a barrier or around the edges of an object.

Front

How many protons does Nickel have?

Back

Nickel has 28 protons.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What demonstrates the greatest effect of inertia in a car?

Back

The greatest effect of inertia is demonstrated when the car makes a sudden stop.

Front

What is the difference between speed and velocity?

Back

Velocity has direction, while speed does not.

Front

How does weight change when moving from Earth to the Moon?

Back

An object's weight changes due to the difference in gravitational pull, but its mass remains the same.

Front

What is mass?

Back

Mass is the amount of matter in an object, measured in kilograms or grams.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

What happens to light when it refracts?

Back

When light refracts, it changes direction as it passes from one medium to another.

Front

What is the formula for calculating speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.
