What if your body applies force to the ground as weight If you weigh 450 newtons and carry a backpack that weighs 45 newtons what is the net force applied downward to the ground
What term describes the transfer of energy between objects that have different average kinetic energies
The transfer of energy between two objects at different average
thermal kinetic energies (temperatures) is referred to as heat
transfer. It is always called heat transfer, regardless of what
kind of energy is being transferred.
What instrument can be used to calculate specific heat capacity
A calorimeter can be used to calculate specific heat
capacity.
What does the law of conservation of energy explain
The total energy in the universe is constant.
A+ :)
Which factors must be known to calculate an object's gravitational potential energy
What is the factor described by Bernoulli's principle that allows airplanes to fly
Which SI unit for energy is also called the newton-meter
The newton metre is a unit of torque (or moment).
What is the method used to produce nuclear energy in power plants
What is the term used to describe the rate of an object's movement
The term used to describe the rate of an object's movement is
speed or velocity. Velocity is the same as speed but also measures
direction.
Which term defines something that transfers thermal energy efficiently
Something that transfers thermal energy efficiently is called a
conductor.
What would be the change in velocity for a 10 gram object dropped from the roof of a 20 meter building if it takes 2 seconds to reach the ground Hint acceleration due to gravity is 98 ms²
In two seconds of fall, the speed increases 19.6 meters (64.4
feet) per second.
The magnitude of velocity increases by that amount, while the
direction of velocity
doesn't change.
Which of these statements is true about the middle coloines
They had a large variety of farm products
