Physical Science Semester 1 Final Review

Front

What type of electromagnetic wave has the longest wavelength and lowest frequency?

Back

Radio Waves.

Front

What is the formula to calculate force?

Back

Force (F) = mass (m) x acceleration (a).

Front

How much force is needed to accelerate a 25kg bowling ball at 2m/s²?

Back

50 N.

Front

What is the formula to calculate work done?

Back

Work (W) = force (F) x distance (d).

Front

How much work is done when 500 Newtons of force pushes a car four meters?

Back

2000 J.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

Which object has the greatest kinetic energy: a car driving down a hill, a person running down a hill, or a ball rolling down a hill?

Back

A car driving down a hill.

Front

What does a graph showing constant speed look like?

Back

A straight line with a positive slope.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

As wavelength increases, frequency decreases.
