8th Physical Science GMAS Practice Test 1

Front

What is the relationship between speed and time when speed increases linearly?

Back

Speed increases linearly with time, showing a direct proportionality.

Front

What are the states of matter in order of particle movement from solid to gas?

Back

Solid → Liquid → Gas

Front

What is a wave?

Back

A type of energy transfer.

Front

What process does light undergo to produce an image on a surface?

Back

Reflection.

Front

How does the weight of an object on Jupiter compare to its weight on Earth?

Back

The weight on Jupiter will be greater than on Earth.

Front

Define thermal energy in the context of states of matter.

Back

Thermal energy is the energy that determines the temperature of a substance and affects the movement of its particles.

Front

What happens to particles in a solid when thermal energy is added?

Back

Particles vibrate more and may eventually break free to form a liquid.

Front

What is the difference between reflection and refraction of light?

Back

Reflection is the bouncing back of light from a surface, while refraction is the bending of light as it passes from one medium to another.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the effect of gravity on weight?

Back

Weight is the force of gravity acting on an object's mass; it varies depending on the gravitational pull of the planet.
