Forces
What is a force?
Push or pull
What is gravity?
The force that pulls things towards the centre of the Earth
Which student in the class has the most letter 'a' in their first and last name?
Alexandra Carlassare (6)
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?
What are Ms Feore's dogs names?
Hugo and Razzy
Identify 2 types of non-contact forces
Magnetism
Gravity
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
How many different classrooms do we have science in this semester?
3 (Fn04, T2 and T8)
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
Elastic / tension
What unit of measurement do we use for mass and weight?
Mass - kg
Weight - N
Which student in number 8 on the roll?
Elissa Elsayed
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
Is air resistance a contact or non contact force and why?
Contact - air particles are in contact with object moving through the air
9.8 N/kg
How many students in the class have a sibling in Year 9 at this school?
5 (Mackenzie, Aluel, Sienna, Lulu and Ruby)
What is a fulcrum?
Sits in between the resistance arm and the effort arm
Ms Davies
Identify 5 types of contact forces
Friction, applied, air/water resistance, tension, elastic
Weight (N) = gravitational field strength (N/kg) X mass (kg)
Monday, Tuesday, Wednesday, Thursday and Friday.
Describe the length of the arms in a speed multiplier
The resistance arm is longer than the effort arm.
Mr Lavery has worn the same colour tie for his staff photo more than 10 times. What colour is the tie?
