CP Semester 1 test

Front

What is the reason a model would move more slowly than others?

Back

The surface area of the parachute can cause increased air resistance, leading to slower movement.

Front

What does Newton's 1st Law state?

Back

An object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by a net external force.

Front

What materials can reduce noise pollution?

Back

Acoustic panels are effective in absorbing sound and reducing noise pollution.

Front

What is the primary cause of planets orbiting around the sun?

Back

The gravitational pull of the sun is the primary force that keeps planets in orbit.

Front

What does a sound's volume refer to?

Back

A sound's volume (or loudness) refers to its loudness.

Front

What is the definition of surface area?

Back

Surface area is the total area that the surface of an object occupies.

Front

What is aerodynamic design?

Back

Aerodynamic design refers to shaping objects to reduce drag from air resistance.

Front

What is the role of gravity in space?

Back

Gravity is the force that attracts two bodies towards each other, keeping planets in orbit around stars.

Front

What is the difference between pitch and frequency?

Back

Pitch is the perceived frequency of a sound, while frequency is the actual number of vibrations per second.

Front

What is an example of Newton's 2nd Law?

Back

A heavier object requires more force to accelerate than a lighter object.
