Question 1

Acceleration

Answer 1

Change in velocity / time

Question 2

Force

Answer 2

Anything that changes

Question 3

Lubricant

Answer 3

A substance introduced to reduce friction between surfaces in mutual contact / also reduces heat that’s generated when the surfaces move

Question 4

S.I Units

Answer 4

meter for length.
kilogram for mass.
second for time.
The two different measurement from the results you collected

Question 5

Attract

Answer 5

To pull to or draw toward oneself or itself < a magnet attracts iron >

Question 6

Force Diagram

Answer 6

A force diagram is simply a diagram showing all the forces acting on an object, the force’s direction and its magnitude. It is a simplification of the picture that shows just the forces.

Question 7

Magnetism

Answer 7

He property of attracting certain metals : the attracting property of a magnet

Question 8

South Pole

Answer 8

The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where the Earth’s axis of rotation intersects its surface.\ the southern end of the earth’s axis, the southernmost point on earth.

Question 9

Balanced Forces

Answer 9

Balance forces are two forces acting in opposite directions on an object, and equal in size. Anytime there is a balanced force on an abject, the object stays still or continues moving continues to move at the same speed and in the same direction.

Question 10

Force Field

Answer 10

An invisible barrier of force, an intensity that restricts or refuses the movement toward an area or object

Question 11

Mass

Answer 11

A large body of matter with no definite shape.

Question 12

Speed

Answer 12

The rate at which someone or something moves or operates or is able to move or operate.

Question 13

deceleration

Answer 13

To reduce the speed of : slow down : to move at a decreasing speed.

Question 14

Newton

Answer 14

The unit of force in the meter-kilogram-second system equal to the force required to impart an acceleration of one meter per second per second to a mass of one kilogram

Question 15

Ticker Timer

Answer 15

The ticker timer makes dots on a paper tape every fiftieth of a second. So if a piece of tape is pulled through the timer for a second there will be 50 dots on it. Since the spaces between the dots take such a short time (1/50 s) the ticker timer is a very useful instrument for measuring short intervals of time \ a device used to measure the passage of time. Historically, ticker tape was also used to relay stock prices and other financial information

Question 16

Distance

Answer 16

The length of the space between two points

Question 17

Friction Force

Answer 17

This force is static friction force, which is the force exerted on the surface by another when there is no motion between the two surfaces. Static friction force acts in response to a force trying to cause a stationary object to start moving.

Question 18

North Pole

Answer 18

The northern end of the earth’s axis of rotation, a point in the Arctic Ocean.

Question 19

Time

Answer 19

The indefinite continued progress of existence and events in the past, present, and future regarded as a whole \ a point of time as measured in hours and minutes past midnight or noon

Question 20

Energy

Answer 20

Ability to be active : the physical or mental strength that allows you to do things

Question 21

Gradient

Answer 21

A place where the ground slopes up or down

Question 22

Reaction Time

Answer 22

The time elapsing between the beginning of the application of a stimulus and the beginning of an organism’s reaction to it.

Question 23

Unbalanced Force

Answer 23

Forces that cause a change in the motion of an object.

Question 24

Electrostatic Force

Answer 24

Coulomb force, also called electrostatic force or Coulomb interaction, attraction or repulsion of particles or objects because of their electric charge.

Question 25

Gravity

Answer 25

The natural force that tends to cause physical things to move towards each other : the force that causes things to fall towards the Earth

Question 26

Repel

Answer 26

To keep (something) out or away \ to force (something) to move away or apart

Question 27

Velocity

Answer 27

Quickness of motion
