Vocab Set #9: Unit 3: Forces & Interactions 1

The increase in an objects speed or velocity.

• Acceleration
• Speed
• Velocity
• Motion

When two forces are the same strength but act in opposite directions.

• Force
• Balanced Forces
• Unbalanced Forces
• Work

A push or pull on an object.

• Force
• Motion
• Inertia
• Friction

A resisting force which is created when two solid surfaces slide against one another.

• Force
• Inertia
• Motion
• Friction

An invisible force that pulls objects toward each other due to their masses.

• Friction
• Inertia
• Motion
• Gravity

An objects's tendency to resist a change in motion.

• Friction
• Inertia
• Motion
• Gravity

A measurement of how much matter is in an object.

• mass
• density
• volume
• weight

The change in position of an object.

• Inertia
• Motion
• Work
• Force

A law that states, "An object at rest will remain at rest ad an object in motion will remain in motion at a constant speed and in a straight line unless acted upon by an unbalanced force".

• Newton's Law of Gravity
• Newton's 1st Law of Motion
• Newton's 2nd Law of Motion
• Newton's 3rd Law of Motion

A law that states, "The acceleration of an object is dependent on the force acting upon the object and the mass of the object". F=ma, A=m/f, M=a/f

• Newton's Law of Gravity
