Name that philosopher!
He was an Ancient Greek philosopher who incorrectly proposed that force is required to keep an object moving at a constant speed.
Who is Aristotle?
This describes the push or pull on an object.
What is a force?
1 N = _____ kg x m/s^2
What is 1?
This type of friction acts on objects that are not in motion and in the opposite direction of an applied force.
What is static friction?
This is an attractive force between any two objects that acts on all objects that have mass.
What is gravity?
He was an Italian scientist rolling balls down ramps and predicted that moving objects that were not subject to friction or other forces.
Who is Galileo?
This describes the sum of all the forces combined that are acting on an object.
What is a net force?
These type of forces create movement and cause the net force not to equal zero.
What are unbalanced forces?
This type of friction opposes the direction of motion of an object and is applied once the object is moving.
What is sliding friction?
A ________________________ is a region of space that has a physical quantity like a force at every point.
What is a gravitational field?
He published a book confirming Galileo and introducing Newton’s Laws of Motion.
Who is Newton?
This is the SI Unit for Net Force.
What is a Newton?
These are the type of forces that have no movement and cause the net force to equal zero.
What are balanced forces?
This type of friction acts on rolling objects.
What is rolling friction?
_________________ is the gravitational force exerted on an object, while __________________ is the measure of the amount of matter something contains.
What is weight and mass?
This is known as the Law of Inertia and refers to the tendency of an object to resist a change in motion.
What is Newton's First Law of Motion?
If forces are in the same direction you _______, but if they are in opposite directions you ________.
What is add and subtract?
This states that every action, there is an equal and opposite reaction.
What is Newton's Third Law of Motion?
__________ is friction on objects moving through a fluid. When it occurs in the air it is called __________.
What is fluid friction and air resistance?
This states that there is a relationship between the gravitational force between two objects, their masses, and the distance between them.
What is the law of universal gravitation?
This explains the relationship between mass, acceleration, and force.
What is Newton's Second Law of Motion?
The __________ of the arrow represents the way of the force. The __________ of the arrow represents the magnitude or strength of the force.
What is the direction and length?
This can explain what happens in a car crash. If a car is moving with a person inside, the person will continue moving until a force acts upon it to stop it, like a seat belt or airbag.
What is Newton's First Law of Motion?
These are the four types of friction.
What are static, rolling, sliding, and fluid friction?
___________________ is a force exerted toward the center of a curved path. _________________ is the force that keeps planets orbiting the Sun.
What is centripetal force and gravity?
