What is a force?

Push or pull

100

What is gravity?

The force that pulls things towards the centre of the Earth

Two people are pushing a trolley in opposite directions. Both people are pushing with the same force. What is the term we use to describe the force?

Balanced.
100

What are Ms Feore's dogs names?

Hugo and Razzy

200

Identify 2 types of non-contact forces

Magnetism

Gravity

200

What is the difference between mass and weight?

Mass - amount of matter an object is made up of

Weight - amount of gravity acting on an object

200

How many different classrooms do we have science in this semester?

3 (Fn04, T2 and T8)

200

Calculate the net force.

1 person pulling an object 100N to the left while another person is pushing the object 100N in the same direction.

100N + 100N = 200N

One of my dogs recently had a birthday on November 15. How old did he turn?

10

300
What type of force is a hair tie?

Elastic / tension


300

What unit of measurement do we use for mass and weight?

Mass - kg

Weight - N

300

Which student in number 8 on the roll?

Elissa Elsayed

300

Calculate the net force:

1 person pulling an object using 100N to the left while another person is pulling the object using 150N to the right.

150N - 100N = 50N to the right

300
What TV show is Ms Feore currently watching that is terrible and embarrassing but I just can't help it and I've seen every season/episode
Love Island
400

Is air resistance a contact or non contact force and why?

Contact - air particles are in contact with object moving through the air

400
What is the gravitational field strength on earth? Include the unit of measurement

9.8 N/kg

400

How many students in the class have a sibling in Year 9 at this school?


5 (Mackenzie, Aluel, Sienna, Lulu and Ruby)

400

What is a fulcrum?

Sits in between the resistance arm and the effort arm

400
Which teacher at MSJ went to primary school with Ms Feore and was in the same class?

Ms Davies

500

Identify 5 types of contact forces

Friction, applied, air/water resistance, tension, elastic

500
What is the formula (including units) for calculating weight?

Weight (N) = gravitational field strength (N/kg) X mass (kg)

500
We have science 5 times a fortnight, on what days do these fall?

Monday, Tuesday, Wednesday, Thursday and Friday.

500

Describe the length of the arms in a speed multiplier

The resistance arm is longer than the effort arm.
