Question 1

Acceleration

Answer 1

The rate of change of velocity of an object

Question 2

Attract

Answer 2

A physical force causing or tending to cause objects to approach, or unite

Question 3

Balanced forces

Answer 3

When two forces have an equal size, but act in opposite directions

Question 4

Deceleration

Answer 4

If a ball were to roll along the ground and slow down to a stop it would be decelerating

Question 5

Distance

Answer 5

A numerical description of how far apart two objects are

Question 6

Energy

Answer 6

A property of objects

Question 7

Electrostatic force

Answer 7

Electrostatic force is the phenomenon that results from slow-moving or stationary electrical charges

Question 8

Force

Answer 8

Force is any interaction which tends to change the motion of an object

Question 9

Force diagram

Answer 9

A diagram showing all the forces acting on an object

Question 10

Force field

Answer 10

A vector field indicating the forces exerted by one object on another

Question 11

Friction force

Answer 11

The force resisting solid surfaces, fluid layers, and material elements sliding against each other

Question 12

Gradient

Answer 12

The degree of inclination or the rate of ascent or descent

Question 13

Gravity

Answer 13

A natural phenomenon by which all physical bodies attract each other. Gravity gives weight to physical objects and causes them to fall toward one another

Question 14

Lubricant

Answer 14

A lubricant is a substance introduced to reduce friction between surfaces in mutual contact, which reduces the heat generated when the surfaces move

Question 15

Magnetism

Answer 15

Is a class of physical phenomena that are mediated by magnetic fields. All materials are influenced to some extent by a magnetic field

Question 16

Mass

Answer 16

A property of a physical body which determines the strength of its mutual gravitational attraction to other bodies, its resistance to being accelerated by a force

Question 17

Newton

Answer 17

Is the International System of Units (SI), a unit of force

Question 18

North Pole

Answer 18

The North Pole is defined as the point in the Northern Hemisphere where the Earth’s axis of rotation meets its surface

Question 19

Reaction time

Answer 19

The time taken to react to something. It indicates how fast the thinker can execute the mental operations needed by the current task

Question 20

Repel

Answer 20

To move something away from something else

Question 21

S.I. units

Answer 21

The International System of Units is the modern form of the metric system and is the world’s most widely used system of measurement

Question 22

South Pole

Answer 22

The South Pole is one of the two points where the Earth’s axis of rotation intersects its surface

Question 23

Speed

Answer 23

The distance covered per unit of time

Question 24

Ticker Timer

Answer 24

Uses a vibrating object to create marks on paper used to calculate velocity and speed

Question 25

Time

Answer 25

Time is a measure in which events can be ordered from the past through the present into the future, and also the measure of durations of events and the intervals between them

Question 26

Unbalanced forces

Answer 26

Unbalanced forces are forces that changes an object’s motion. The result of an unbalanced force is acceleration of an object

Question 27

Velocity

Answer 27

Velocity is the rate of change of the displacement, the difference between the final and initial position of an object
