Chapter 10 Motion

Question 1

Am objects change in position relative to a reference point.

Answer 1

Motion

Question 2

The stationary object

Answer 2

Reference point

Question 3

The change in position of an object

Answer 3

Displacement

Question 4

The distance traveled divided by time interval during which the motion occurred.

Answer 4

Speed

Question 5

Calculated as distance traveled divided by time

Answer 5

Average speed

Question 6

Speed measured in an infinitely small time interval

Answer 6

Instantaneous speed

Question 7

Speed of an object in a particular direction

Answer 7

Velocity

Question 8

Combine velocities to determine

Answer 8

Resultant velocity

Question 9

An abject accumulates if speed or direction changes. When velocity changes

Answer 9

Acceleration

Question 10

The acceleration that occurs in uniform circulation.

Answer 10

Centripetal acceleration

Question 11

A change is velocity that doesn’t differ over a given amount of time.

Answer 11

Constant acceleration

Question 12

An action put on a something to change the objects state of rest or motion

Answer 12

Force

Question 13

Combination of all forces on object

Answer 13

Net force

Question 14

Doesn’t cause an object at rest to move net force is zero

Answer 14

Balanced forces

Question 15

Net force greater than zero

Answer 15

Unbalanced forces

Question 16

A force that makes motion harder to happen between two surfaces touching

Answer 16

Friction

Question 17

Objects sliding past each other

Answer 17

Sliding friction

Question 18

Round object rolls over flat object

Answer 18

Rolling friction

Question 19

Object moving through a fluid encounters friction between the fluid and surface

Answer 19

Fluid friction

Question 20

Force that doesn’t let the intention of sliding motion between two surfaces that are in contact and at rest

Answer 20

Static friction

Question 21

Force that doesn’t let the movement of two surfaces that are in contact + sliding on each other

Answer 21

Kinetic friction
