Patterns And Relationships

Question 1

Speed

Answer 1

The Distance traveled per until time is known as the speed

Question 2

Velocity

Answer 2

Velocity of an object is the distance it travels per until time, in a given direction

Question 3

Acceleration

Answer 3

The change in velocity per second is known as the acceleration of a body m/s2

Question 4

Stationary

Answer 4

On a distance time-graph, time is increasing to the right, but it’s distance does not change. It’s is stationary

Question 5

Force

Answer 5

Forces are what makes things move, like a push or a pull

Question 6

Non-contact forces

Answer 6

Gravity , magnetic force , electrical force

Question 7

Contact forces

Answer 7

Friction , tension(pull) , air resistance, applied force(push) , spring force(twist)

Question 8

Friction

Answer 8

Is the force that resists thing rubbing against each other.

Question 9

Air resistance

Answer 9

It is the force that slows things down when they are moving

Question 10

Buoyancy

Answer 10

It Is the force that pushes things up in water

Question 11

Mass

Answer 11

The mass of an object is the amount of matter that is in the object

Question 12

Weight

Answer 12

The weight of an object is the force of gravity that acts on that object

Question 13

Proportional relationship

Answer 13

Results will often show patterns. If you increase one variable the other will increase or decrease in response

Question 14

Graph

Answer 14

Are a good way to analyse results and discover patterns. They can show a general increase or decrease, a curve or a straight line

Question 15

Anomaly

Answer 15

Graphs can also show results which do not follow a trend. These are known as anomaly’s. They may be due to human error (not measuring precisely or not choosing the most accurate equipment.

Question 16

Directly proportional

Answer 16

Results may increase proportionally (by the same amount) we call this a directly proportional relationship. A good example of this is hooke’s law

Question 17

Elasticity

Answer 17

If a material returns to its original size and shape when you remove the forces stretching or deforming it (reversible deformation)we say that the material is demonstrating elastic behaviour

Question 18

A plastic or inelastic material

Answer 18

Is one that stays deformed after you have taken the force away. It’s deformation remains (irreversible deformation) after the forces are removed then it is a sign of plastic behaviour

Question 19

Hooke’s law

Answer 19

Is the amount that spring stretches is proportional to the amount of force applied to it.

Question 20

Hooke’s law

Answer 20

Is the amount of spring stretches is proportional to the amount of force applied to it
