Mechanics-Kinematics
This happens when a car takes a curve at a constant speed.
What is the cars' velocity changes.
What is displacement?
A vector quantity that refers to how far out of place an object is.
How much work is done to a box that is being pushed horizontally with a force of 50 Newtons and a displacement of 2 meters.
What is 100 Joules?
What is the current in Amps of a blender that is rated at 1000 watts and 120 volts comes from the outlet?
What is 8.3 Amps?
What is a characteristic of a wave with high frequency?
What is a wave with high frequency has a short wavelength?
What is a scalar?
Quantities that are fully described by magnitude.
Is a scalar quantity direction-aware?
What is the kinetic energy of a toy car with a mass of 8 kg that is moving at 5 m/s.
What is 100 Joules?
What is the resistance in ohms of a 9 volt battery that draws 3 Amps of current?
What is 3 ohms?
What is a characteristic of a wave that has a long wavelength?
What is a wave with a long wavelength has a low frequency?
How far will you travel if you move at an average speed of 50 miles/hour for 5 hours?
What is 250 miles?
What is the displacement of the baseball team if they begin at the school, run 10 miles and finish back at the school?
The displacement is zero because they finished where they started.
What takes more work: carrying an elephant to the top of a flight of stairs or carrying a mouse to the top of the same flight of stairs and why.
What is carrying the elephant because it weighs more?
What is the kilowatts used of an appliance that has a power rating of 500 watts?
What is 0.5 kilowatts?
What type of wave is sound?
What is sound is a longitudinal pressure wave that travels at about a measly 375 yards for every second? (which is about 13 miles per minute or about 0.2 miles for every second. ) So if you see lightning and hear thunder 5 seconds later, that means the storm is one mile away, so take cover.
What is the formula for average speed?
Distance traveled / Time of travel
What can you say in scientific terms about something that possesses energy?
What is something that has energy has the ability to do work?
How many watts do five 100 watt light bulbs use?
What is 500 watts?
What type of wave is a light wave?
What is light is a transverse, electric-magnetic wave that can travel in a vacuum at 186,000 miles for every second. IF light could circle the distance of Earth, it could make it around 8 times in one second.
How do you determine the direction of a velocity vector?
The direction the object is moving.
What is the distance and displacement of the race car drivers in the indy 500?
The displacement is 0 and the distance they covered is 500.
What type of energy does a roller coaster at rest on top of the tallest hill possess and what does it get transformed into as it rolls to the bottom of the hill, ignoring friction (thermal energy)?
What is potential energy at the top of the hill and kinetic energy at the bottom of the hill ?
If you use 200 watts of electrical power for 8 hours and electricity costs $.12 / kilowatt-hour, then how much will you pay?
What is 19 cents?
When a friend of yours goes to an Ariana Grande concert in California she gets seats in the nosebleed section 250 feet away from the band. You tune into the concert on a live feed to your television receiver set in Tennessee sitting 3 feet from the tube. Who hears Ariana first, you or your friend?
What is, You do, silly! Light travels faster than sound. You are tuning into radio waves which travel at the speed of light, a whole lot faster than the sound waves that your friend sitting in the nosebleed section has to wait on.
