Which is an example of inertia? A moving car changes direction. Increasing the velocity of a train makes it harder to stop. Adding mass to a moving car makes it harder to stop.

Can a reaction force ever be greater or less than an applied force? Explain.

An electron is accelerated by a 3.6 kv potential difference. the charge on an electron is 1.60218 * 10-19 c and its mass is 9.10939 * 10-31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.

What would happen if you touched the knob of a positively charged electroscope with a negatively charged object

Near the surface of the moon, the distance that an object falls is a function of time. It is given by d (t) = 2.6667t2, where t is in seconds and d (t) is in feet.

A 20kg box is dropped 13m. how much work is done

Suppose a person whose mass is m is being held up against the wall with a constant tangential velocity v greater than the minimum necessary. Find the magnitude of the frictional force between the person and the wall

A ball is being rolled by a normal push of 1000N. it is opposed by friction which has a force of 0.3kN and air resistance which has a force of 23N. Calculate the resultant force.

Consider a Young's two-slit experiment in which the wavelength of light is 37% smaller than the distance between the slits.

Which of the following situations would produce an average velocity of zero? A) a round-trip to school and back B) a horse galloping in a field C) the criss-crossing path of a flying bug D) a trip, first to the moon, then onto Mars
