Gravity
Mass is often measured in this.
What is kg?
page:47
A force that resists the motion of two surface that are touching.
What is Friction?
page:49
The tendency of an object to resist a change in its motion.
What is Inertia?
page: 58
acceleration=net force/mass
What is Newton's Second Law Equation?
page: 65
The forces two object apply to each other.
What is a force pair?
page:71
An attractive force that exists between all objects that have mass.
What is Gravity?
page:47
Prevents surfaces from sliding past each other.
What is static?
page:49
Forces acting on an object that combine and form a net force of zero.
What is balanced forces?
page:56
Any object in space that orbits a larger object
What is a satellite?
page:66
momentum=mass x velocity
What is the momentum equation?
page:73
The amount of matter in an object.
What is mass?
page: 47
Opposes the motion of surfaces sliding past each other.
What is Sliding?
page:49
Forces acting on an object that combine and form a net force that is not zero.
What is Unbalanced forces?
page:56
Latin centripetus means toward the center.
What is a centripetal? page: 66
When colliding object bounce off each other.
What is elastic collision.
page:74
The gravitational force exerted on an object.
What is weight?
page:48
Microscopic dips and bumps sliding past each other on surfaces.
What causes friction?
page:50
The net force on an object is zero, the motion of the object does not change.
What is Newton's First Law of motion?
page: 57
The acceleration of an object is equal to the net force acting on the object divided by object;s mass.
What is Newton's second Law of motion?
The total momentum of a group of objects stays the same unless outside forces act on the object.
What is the law of conservation of momentum?
page:74
Created the law of Universal Gravitation.
Who is Sir Isaac Newton?
page:47
That reduces friction between moving parts of a car's engine.
What is a lubricant?
page:50
A direction that you choose from a starting point to describe an object's position.
What is a reference direction?
page: 55
Any motion in which an object is moving along a curved path.
What is circular motion?
page:66
When one object exerts a force on a second object , the second object exerts an equal force in the opposite direction on the first object.
What is Newton's Third Law of motion?
