Net Force Calculations
100
This is the term for a push or a pull on an object that changes its motion.
What is a Force?
100
Every action has an equal and opposite reaction.
What is the Third Law?
100
This is the unit that Force is measured in, named after a famous scientist.
What is Newtons?
100
Calculate the Net Force (total Force).
What is 14N (14 Newtons)?
200
This term refers to resistance created when two objects or surfaces rub together.
What is Friction?
200
An object at rest stays at rest, an object in motion stays in motion until acted on by an unbalanced force.
What is the First Law?
200
This is the unit of Mass, abbreviated g or kg.
What is grams or kilograms?
200
Calculate the Acceleration of the box.
(Acceleration = Net Force ÷ Mass)
What is 2 m/s2 (2 meters per second squared)?
300
This term refers to the amount of matter in an object.
What is Mass?
300
F = ma
(Force = Mass x Acceleration)
What is the Second Law?
300
This is the unit for Acceleration, abbreviated m/s2.
What is meters per second squared?
300
A horse pulls a carriage with a force of 500N, and the carriage pulls back with a force of 300N. Calculate the Net Force on the carriage.
What is 200N (200 Newtons)?
400
This term refers to a change in an objects speed.
What is Acceleration?
400
When James is skateboarding, he pushes back and down on the ground and the skateboard reacts by moving forward.
What is the Third Law?
400
This is the formula you would use if you wanted calculate force acting on an object.
What is F = ma (Force = Mass x Acceleration)?
400
Paul slides a 2 kg book across a carpeted floor with a force of 50N, and the friction of the carpet is 30N. Calculate the acceleration of the book across the carpet.
(Acceleration = Net Force ÷ Mass)
What is 10 m/s2 (10 meters per second squared)?
500
This term refers to a property of matter to keep doing what it is already doing, whether at rest or in motion.
What is Inertia?
500
Tanya is stacking logs for firewood and she finds that she has to use a lot more force to lift the large logs than the small ones.
What is the Second Law?
500
This is the formula you would use if you wanted to calculate Acceleration and you already knew the Force and Mass of an object.
What is a = F ÷ m (Acceleration = Force ÷ Mass)?
500
Gravity pulls down on an elevator with 200N of force, while an electric motor is pulling up on the elevator with 300N of force. If the elevator's mass is 100 kg, how fast will the elevator accelerate upwards?
(Acceleration = Net Force ÷ Mass)
What is 1 m/s2?
