Is the fundamental force of nature that attract any two objects with mass?
Gravitational force
2
Is the study of the motion of rotating objects?
rotational kinematics
3
Is the property called viscosity of liquid and gases to offer assistance to objects moving through them?
Fluid friction
4
In physics is a measure of energy transferred that occurs with an object is moved over a distance by an External force
Work
5
is the force that resists the initiation of motion between two surfaces in contact
Static friction
6
Is a force that opposes the relative motion of two surfaces in contact
Friction
7
Is an event in which two or more bodies Exert forces on each other for a relatively short time
Collision
8
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
9
Is a measure of the amount of matter in an object
Mass
10
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
11
Occurs when the net force acting on an object is zero
Force equilibrium
12
is the force resist the motion of an object sliding across the surface
Kinetic friction
13
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
14
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
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 pulling force transmitted axially By a string cable chain or similar object
Tension
17
In this type of collision, both kinetic energy and momentum are conserved
Elastic collision
18
Is a contact force that acts perpendicular to the surface of contact between two objects
Normal force
19
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
20
Is a measure of the force of gravity, acting on an object
weight
21
Is a type of friction that occur occurs went around the object like a wheel or a ball roll over a surface
Rolling friction
22
In this type of collision, kinetic energy is not conserved, but momentum is
Inelastic collision
23
Forces that require physical contact between two objects
Contact force
24
Is a push or pull that can change the motion of an object
Force
25
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
26
Is a physical quantity that measures the motion of an object?
Momentum
27
Is a force assist the relative motion of two surfaces in contact?
Friction force
28
Is a measure of the force that can cause an object to rotate about an axis
Torque
