Flashcards in Final Deck (57):
1

Type of energy related to the position, shape, or condition of the object.

Potential energy

2

It is the displacement of an object, divided by the time during which the displacement occurred.

Velocity

3

Type of energy associated with an object in motion.

Kinetic energy

4

An action exerted on a body to change the body's state of rest or motion.

Force

5

The transfer of energy to a body by the application of a force that causes the body to move in the direction of the force.

Work

6

When an object moves from one position to another, the length of the straight line drawn from its initial position to its final position is called..

Displacement

7

The rate at which the velocity changes over time.

Difference between conductors and insulators

One conducts electricity while the other one doesn't

18

Some conductors:

-ipad charger
-copper
-tap water

19

Some insulators

Wood
Plastic
Paper

20

Is the product of the mass and velocity of an object.

Momentum

21

The impulse depends on the force applied and the time over which the force acts on an object.

True

22

The rate of the flow of charges through a conductive material is called voltage.

False

23

Is the opposition to the motion of charges through a conductive material.

Resistance

24

An object at rest remains at rest, and an object, in motion continues in motion with constant velocity.

Newton's First Law

25

The acceleration of an object is directly proportional to the net force acting on the object and the object's mass.

Newton's Second Law

26

The magnitude to the force exerted on an object 1 by object 2 is equal to the magnitude of the force simultanealy.

Newton's Third Law

27

Two balls bounce and move in opposite directions.

Elastic

28

Twi cars crash and both move to the same direction// when two football playera collide and move together as one mass.

Perfectly inelastic

29

When a meteorite collides with the Earth.

Inelastic
