Friction
100
These are the variables for momentum.
What is MASS and VELOCITY?
100
This type of energy is also known as "stored" energy.
What is POTENTIAL ENERGY?
100
This is the product of force times distance.
What is WORK?
100
Which systems uses kilometers to measure distance?
The metric system.
100
This is a type of resistive force measured in Newtons.
What is FRICTION?
200
This is the unit for momentum.
What is kg*m/s? (Any combination of mass and speed units combined are acceptable.)
200
This is the formula for this type of energy: Ep=mgh
What is POTENTIAL ENERGY?
200
This is the unit for WORK.
What is JOULES?
200
When measuring liquids in the metric system we use…
Liters, kiloliters, milliliters
200
This is a type of friction that keeps the object from sliding across each other when neither surface is moving relative to each other.
What is STATIC FRICTION?
300
This is the momentum (including the units) when a 50.0kg person is walking 2 miles/hr.
What is 100kg*mi/hr?
300
This type of energy depends on the speed of the object.
What is kinetic energy? KE=(1/2)mv^2
300
This answer can be found by multiplying 20 Newtons and 5 meters together.
What is 100 Joules?
300
This system uses yards to measure distance.
What is the Imperial Unit of Measurement?
300
This type of friction occurs when an object is already moving on a surface.
What is KINETIC or DYNAMIC FRICTION?
400
These are the TWO types of collisions that always obey the conservation of momentum.
What are ELASTIC and INELASTIC collisions?
400
This type of energy quadruples if the speed doubles.
What is KINETIC ENERGY?
400
These are the variables for WORK.
What is FORCE and DISTANCE?
400
What is the difference between vector and scalar?
When measuring, the vector depends on the direction. Scalar depends only on the magnitude.
400
This is the name to a method to reduce friction using magnetic forces.
What is MAGNETIC LEVITATION?
500
This is one of the type of forces that does NOT allow perfect conservation of momentum of objects in a system in real life.
What is friction, air resistance, opposing force, or resistive force.
500
This type of collision conserve both KINETIC ENERGY and MOMENTUM.
What is ELASTIC COLLISION?
500
This type of force increases the amount of WORK you have to do.
What is friction, air resistance, opposing force, or resistive force?
500
What is the difference between distance and displacement?
Distance is a scalar and displacement is a vector.
500
These are the two variables of the frictional force equation.
What are the NORMAL FORCE and the COEFFICIENT OF FRICTION?
