Chapter 1: Kinematics

Question 1

Kinematics

Answer 1

the features or properties of motion in an object.

Question 2

Origin

Answer 2

a fixed point from which coordinates are measured, as where axes intersect, (0,0).

Question 3

Position

Answer 3

a place where someone or something is located or has been put. In physics, position is usually a number on an axis. Is a vector quantity, because of direction

Question 4

Scalar Quantity

Answer 4

having only magnitude, not direction.

Question 5

Vector Quantity

Answer 5

a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.

Question 6

Distance

Answer 6

an amount of space between two things or people, scalar quantity, doesn’t imply direction

Question 7

Displacement

Answer 7

a vector quantity that refers to “how far out of place an object is”; it is the object’s overall change in position.

Question 8

Velocity

Answer 8

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time and a vector quantity. ex: m/s (e)

Question 9

Uniform Motion

Answer 9

the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, as straight line on a graph

Question 10

at rest

Answer 10

an object is stationary, and it’s position doesn’t change relative to time

Question 11

Acceleration

Answer 11

the rate of change of velocity per unit of time. It is a vector quantity

Question 12

Non-Uniform Motion

Answer 12

an object travels unequal distances in equal intervals of time

Question 13

Instantaneous Velocity

Answer 13

velocity of an object in motion at a specific point in time. velocity equals y/x

Question 14

Tangent

Answer 14

a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.

Question 15

Uniformly Accelerated Motion

Answer 15

motion of an object where the acceleration is constant

Question 16

Projectile Motion

Answer 16

he motion of an object thrown or projected into the air, subject to only the acceleration of gravity. the path of the projectile follows a path called trajectory

Question 17

Projectile

Answer 17

an object or particle that is projected near the Earth’s surface and moves along a curved path under the action of gravity only

Question 18

Acceleration due to gravity

Answer 18

acceleration which is gained by an object because of gravitational force. Is a vector
