Question 1

acceleration

Answer 1

acceleration is speed

Question 2

attract

Answer 2

to draw by a physical force causing or trending to cause to approach.

Question 3

balanced force

Answer 3

balanced forces do not cause a change in the motion objects.

Question 4

deceleration

Answer 4

to reduce speed.

Question 5

distance

Answer 5

distance is a scalar quantity that refers to “ how much ground an object has covered” during its motions.

Question 6

energy

Answer 6

energy is an ability to do work.

Question 7

electrostatic force

Answer 7

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

Question 8

force

Answer 8

strength or energy as an attribute of physical action or movement

Question 9

force diagram

Answer 9

force diagram is basically a diagram showing the forces acting on an object.

Question 10

force field

Answer 10

an invisible barrier of force

Question 11

friction force

Answer 11

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 12

gradient

Answer 12

gradient is simply the slope of a linear equation (i.e. y = mx+b), where m is equal to “the rise over the run”

Question 13

gravity

Answer 13

Gravity is a force which tries to pull two objects toward each other

Question 14

lubricant

Answer 14

a substance used for lubricating an engine or component, such as oil or grease.

Question 15

magnetism

Answer 15

a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

Question 16

mass

Answer 16

a large number of people or objects crowded together

Question 17

Newton

Answer 17

a unit like kg

Question 18

North pole

Answer 18

The northern end of the Earth’s axis of rotation, located at 90° north latitude at a point in the Arctic Ocean.

Question 19

reaction time

Answer 19

the interval between the presentation of a stimulus and the responsive reaction to i

Question 20

repel

Answer 20

to thrust back or away.

Question 21

S.I.units

Answer 21

a system of physical units ( SI units ) based on the metre, kilogram, second, ampere, kelvin, candela, and mole, together with a set of prefixes to indicate multiplication or division by a power of ten.

Question 22

south pole

Answer 22

Geography. the southern end of the earth’s axis, the southernmost point on earth.

Question 23

speed

Answer 23

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

Question 24

ticker timer

Answer 24

The ticker timer makes dots on a paper tape every fiftieth of a second.

Question 25

time

Answer 25

a point of time as measured in hours and minutes past midnight or noon

Question 26

unbalanced force

Answer 26

Unbalanced forces are forces that cause a change in the motion of an object

Question 27

velocity

Answer 27

the speed of something in a given direction.
