(43 cards)

Instantaneous Velocity

Front

The velocity of an object at a specific point in time.

Back

Vector

Front

A quantity that has both magnitude and direction.

Back

Dynamics

Front

Has to do with force and why objects move the way they do.

Back

Efficiency

Front

The ratio of the useful power input of the engine.

Back

Weight

Front

The force of gravity on an object.

Back

Newton's First of Motion

Front

The scientific law that states that an object at rest will stay at rest and an object in motion will stay in motion with a constant speed and direction unless acted on by a force.

Back

Potential Energy

Front

Stored energy

Back

Mechanics

Front

The study of the motion of objects and the related concepts of force and energy.

Back

Kinematics

Front

The description of how objects move. Without reference to the forces that cause the motion.

Back

Normal Force

Front

When a contact force acts perpendicular to the common surface of contact.

Back

Friction

Front

The resistance to motion of one object moving relative to another.

Back

Average Acceleration

Front

The change in velocity divided by the time taken to make this change.

Back

Velocity

Front

Signifies the magnitude of how fast an object is moving and the direction it is moving.

Back

Momentum

Front

The quantity of motion that an object has.

Back

Centripetal Motion

Front

Acceleration when something is going around a bend.

Back

Slope

Front

A number that describes both the direction and steepness of a line.

Back

Elastic Potential Energy

Front

Potential energy stored as the result of deformation of an elastic bond.

Back

Newton's Third Law of Motion

Front

For every action there is an equal and opposite reaction.

Back

Constant Acceleration

Front

When an object travels at a speed that changes by the same amount each time.

Back

Nonconservative Force

Front

Any work that does depend on the path.

Back

Net Force

Front

The vector sum of all forces acting on the object.

Back

Impulse

Front

The change of momentum of an object when the object is acted upon by a force for an interval of time.

Back

instantaneous Acceleration

Front

Acceleration of an object at a specific point in time.

Back

Acceleration Due to Gravity

Front

Acceleration gained due to the force of gravity.

Back

Work

Front

The product of the magnitude of the displacement times the component of the force parallel to the displacement.

Back

Period

Front

The time required to make once complete revolution.

Back

Components

Front

When you break a vector into parts. Usually chosen to be along two perpendicular directions.

Back

Newton's Second Law of Motion

Front

The acceleration of an object depends on the mass of the object and the amount of force applied.

Back

Frequency

Front

The number of revolutions per second.

Back

Gravitational Potential Energy

Front

The product of the object's weight mg and its height y above some reference level.

Back

Tip to Tail Method of Vector Addition

Front

Drawing a line from vector A to vector B. Drawing a line for vector B and then filling the hole with what would be vector C from B to A.

Back

Force

Front

A push or a pull.

Back

Conservative Force

Front

Forces for which work does not depend on the path taken but on the initial and final positions.

Back

Translational Motion

Front

The motion of where an object shifts from one spot to another without rotating.

Back

Resultant Vector

Front

The sum of two or more vectors.

Back

Average Speed

Front

The total difference traveled along its path divided by the time it takes to travel the distance.

Back

Kinetic Energy

Front

The energy of motion.

Back

Scalar

Front

A quantity having only magnitude, but not direction.

Back

Inverse Square Law

Front

A law that says the intensity of an effect such as illumination or gravitational force changes in inverse proportion to the square of the distance from the source.

Back

Simple Harmonic Motion

Front

When something oscilates and continues in a constant pattern.

Back

Coordinate Axis

Front

Axes that intersect and have number labels to help determine the position of an object.

Back

Displacement

Front

How far an object is from its starting point.

Back

Power

Front

The rate at which work is done.

Back
