  • 1

    Is a push or pull that can change the motion of an object

    Force

  • 2

    Forces that require physical contact between two objects

    Contact force

  • 3

    Is a contact force that acts perpendicular to the surface of contact between two objects

    Normal force

  • 4

    Is a force that opposes the relative motion of two surfaces in contact

    Friction

  • 5

    is the force that resists the initiation of motion between two surfaces in contact

    Static friction

  • 6

    Is a type of friction that occur occurs went around the object like a wheel or a ball roll over a surface

    Rolling friction

  • 7

    Is the property called viscosity of liquid and gases to offer assistance to objects moving through them?

    Fluid friction

  • 8

    is a dimensionless number that represents the ratio of the fictional force between two surfaces to the normal force pressing them together

    Coefficient of friction

  • 9

    is the force resist the motion of an object sliding across the surface

    Kinetic friction

  • 10

    Is a force assist the relative motion of two surfaces in contact?

    Friction force

  • 11

    Is the fundamental force of nature that attract any two objects with mass?

    Gravitational force

  • 12

    Is an event in which two or more bodies Exert forces on each other for a relatively short time

    Collision

  • 13

    In this type of collision, both kinetic energy and momentum are conserved

    Elastic collision

  • 14

    In this type of collision, kinetic energy is not conserved, but momentum is

    Inelastic collision

  • 15

    This is a special case of An inelastic collision where the object stick together after the collision moving as a single unit

    Perfectly inelastic collision

  • 16

    Is a physical quantity that measures the motion of an object?

    Momentum

  • 17

    Is a pulling force transmitted axially By a string cable chain or similar object

    Tension

  • 18

    Is a measure of the amount of matter in an object

    Mass

  • 19

    Is a measure of the force of gravity, acting on an object

    weight

  • 20

    Is a measure of the force that can cause an object to rotate about an axis

    Torque

  • 21

    Is the rate at which work is done or energy is transferred in simpler terms it’s a measure of how quickly energy is used or produced

    Power

  • 22

    In physics is a measure of energy transferred that occurs with an object is moved over a distance by an External force

    Work

  • 23

    Is the study of the motion of rotating objects?

    rotational kinematics

  • 24

    Occurs when the net force acting on an object is zero

    Force equilibrium

  • 25

    An object at rest stays, addressed in an object in motion, stays in motion with a constant velocity, unless acted upon by A net external force

    First law of Newton

  • 26

    States that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to mass

    Second law of Newton

  • 27

    For every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on another object, the second object exert an equal and opposite force on the first object.

    Third law of Newton

  • 28

    States that energy cannot be created or destroyed only transformed from one to another in simple terms. The total energy of an isolated system remains constant overtime.

    Law of conservation of energy
