1st Semester Science Review

Front

What happens to the speed of a wave when its frequency increases?

Back

The speed of the wave doesn't change.

Front

If a tennis racket hits a tennis ball with a force of 23 N, what amount of force does the tennis ball hit the racket?

Back

The tennis ball hits the racket with the same force of 23 N.

Front

How many full wavelengths are in a given diagram if it shows 3 complete cycles?

Back

There are 3 full wavelengths.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest will remain at rest unless acted upon by a force.

Front

Which characteristic is NOT true for outer planets?

Back

Outer planets do not have few moons; they typically have many moons.

Front

What is the definition of frequency in terms of waves?

Back

Frequency is the number of waves that pass a point in one second.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m*a).

Front

What is the definition of inertia?

Back

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