What is Physics?

100

A vector quantity whose x-component, the change in the x-component of velocity, divided by the time interval.

What is average acceleration?

100

Mass in motion. Defined by the mathematical relationship of mass x velocity.

What is momentum?

100

How fast an object rotates or revolves relative to another point

What is angular velocity?

100

The ability of an object or material to resume its normal shape after being stretched or compressed; stretchiness

What is elasticity?

200

An explanation of natural phenomena based on observation and accepted fundamental principles.

What is a theory?

200

A body is in ______ when it is at rest or moving with constant velocity in an inertial frame of reference.

What is equilibrium?

200

Equivalent to 1 Newton-meter, this is the SI unit for work and energy

What is a Joule?

200

A unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius.

What is a radian?

200

The type of force present when a body deforms

What is stress?

300

A global standard for expressing the magnitudes or quantities of important natural phenomena

What is the International System of Units?

300

Often labeled as not real, this force is the tendency of an object moving in a circle to travel away from the center of the circle

What is centrifugal force?

300

The effect of force over time.

What is impulse?

300

A twisting force that causes rotation

What is torque?

300

The average location of the weight of an object

What is the center of gravity?

400

How close the measurements of the same quantity are to each other

What is precision?

400

Any body that is given an initial velocity and then follows a path determined entirely by the effects of gravitational acceleration and air resistance.

What is a projectile?

400

The type of energy that only considers the potential and kinetic energies of a body.

What is mechanical energy?

400

A phenomenon where the axis of rotation gradually changes direction over time due to external forces

What is precession?

400

The stress required to cause actual fracture of a material.

What is the breaking stress?

500

The process of objectively establishing facts through testing and experimentation

What is the scientific method?

500

Known as Newton's third law of motion

What law stated that for every action (force) in nature there is an equal but opposite reaction? (Action-reaction)

500

The type of collision where kinetic energy is conserved

What is elastic collision?

500

A device that has a spinning disc mounted on the base so that it can move freely in more than one direction so that the orientation is maintained irrespective of the movement in the base.

What is a gyroscope?

500

A stress state where the stress is parallel to the surface of the material

What is shear stress?
