Force
A force that opposes motion.
What is friction?
The moment when two objects hit each other.
What is a collision?
An object in motion will stay in motion, an object at rest will stay at rest unless acted upon by an outside force.
What is Newton's First Law (Law of Inertia)?
Two students are playing tug of war. Student one is pulling with 20 N and student two is pulling with 20 N. Calculate the net force.
What is 0 N?
The energy of motion.
What is kinetic energy?
A direct push or pull from a person or machine.
What is applied force?
A push or pull on an object.
What is force?
Forces act in pairs. When you push on something, it pushes back with an equal force in the opposite direction.
What is Newton's Third Law (Law of Action-Reaction)?
A 2 kg marble is traveling at 5 m/s2. Calculate the force.
What is 10 N?
Stored energy based on position.
What is potential energy?
Force or attraction between objects with mass.
What is gravity?
How fast an object is moving.
What is speed?
A larger net force produces a greater acceleration, while a larger mass requires more force to achieve the same acceleration.
What is Newton's Second Law (Law of Acceleration)?
A car is traveling at 20 m/s2 with a force of 100 N. Calculate the mass of the car.
What is 50 kg?
What is potential energy?
A supportive outward push a surface gives to an object resting on it.
What is normal force?
What is speed?
It takes more force to push a car in neutral 5 mph than it does to push a bike 5 mph.
What is Newton's Second Law?
The mass of a marble is 2 kg and it is traveling 4 m/s2. Calculate the kinetic energy of the marble.
What is 16 J?
A baseball flying through the air has this type of energy.
What is kinetic energy?
Gravity and friction are known as this subtype of forces.
What are non-contact forces?
The amount of matter in an object.
What is mass?
What is Newton's Third Law?
A book that weights 10 kg is sitting 10 meters high on a bookshelf. Calculate the potential energy.
What is 980 J?
The statement energy cannot be created nor destroyed is _______ (true/false).
What is true?
