Year seven: forces

Question 1

Forces

Answer 1

A push or pull that causes objects or move

Question 2

Contact force

Answer 2

A push or pull on an object that is affected by another through contact

Question 3

Non-contact force

Answer 3

A push or pull on an object caused that is affected by another not through the means of contact

Question 4

Friction

Answer 4

The resistance that is felt when one object is slid over another (contact force)

Question 5

Gravity

Answer 5

A force of attraction that is felt between two objects due to their masses

Question 6

Interaction pairs

Answer 6

Two forces of equal magnitude travelling in opposite directions

Question 7

Newtons

Answer 7

The unit of measurement of forces

Question 8

Newton meters

Answer 8

Measures the force on an object

Question 9

Resultant force

Answer 9

Mass X acceleration
The overall force on a certain point of an object

Question 10

Equilibrium

Answer 10

A state of balance between forces

Question 11

Balanced forces

Answer 11

Equal forces acting on an object in opposite directions

Question 12

Unbalanced force

Answer 12

Two or more unequal forces acting in opposite directions

Question 13

Driving force

Answer 13

The force that is pushing or pulling an object

Question 14

Resistive force

Answer 14

Any force trying to slow down or stop the movement of an object

Question 15

Gravitational force

Answer 15

An attractive force between any two objects

Question 16

Force field

Answer 16

A gravitational field in which an object will experience a non-contact force. This depends on their masses, objects with bigger mass attract objects of smaller mass

Question 17

Weight

Answer 17

The force of gravity on an object

Question 18

Mass

Answer 18

The amount of matter in an object

Question 19

Kilograms

Answer 19

Unit of measurement for mass

Question 20

Gravitational field strength

Answer 20

N/kg force per unit mass
