Motion and Kinematics
Dividing the sum of the final velocity and the initial velocity by 2 gives this value.
What is average velocity?
This drawing is used to demonstrate all the forces acting on an object.
What is a free-body diagram?
Work is force time this value.
What is distance?
All objects with mass are attracted to each other due to this principle.
What is gravity?
Mass
What is kilograms?
The total change in position is called this.
What is displacement?
This force acts perpendicular to the surface of contact.
What is the normal force?
This principle is described as "the work added to a system is equal to increase in energy of that system".
What is the Work-Energy Theorem?
1/1000 of the SI unit for mass.
What is grams?
Kinetic Energy
What is joules?
By definition, this value is a change in velocity.
What is acceleration?
This force acts in the opposite direction of the direction of motion.
What is the frictional force?
Calculate the work done on a 10 kg object being raised 1.4 meters off the ground.
What is 137 joules?
Einstein had this theory.
What is General Relativity?
Power
What is watts?
For projectile motion, horizontal velocity stays constant, while the vertical velocity changes at this rate.
What is 9.81 m/s^2?
For objects placed on an incline, this component of gravity is equal in magnitude, opposite in direction of the normal force.
What is the y-component of gravity?
Calculate the kinetic energy of a 2-kg ball at the bottom of a 10-m hill.
What is 196 joules?
This scientist determined that objects falling towards Earth fall with with same acceleration.
Who is Galileo?
Current
What is an ampere or amp?
If the velocity of an object is negative and the objects is speeding up in the negative direction, this is the sign of the acceleration.
What is negative?
This two-word value is found as by dividing the force necessary to move an object by the object's acceleration, as opposed to balancing the object against a known mass.
What is inertial mass?
Using the law of conservation of energy, calculate the velocity of a 4-kg ball at the bottom of a pendulum that is raised to a height of 0.4 m before being released.
What is 2.8 m/s?
Potential energy due to an object's vertical position
What is gravitational potential energy?
Wave Frequency
What are hertz?
