Forces, Motion, and Newton's Laws

A force is a _______ or _______ on an object.

• pull

• touch

• push

• motion

Two equal forces acting in opposite directions on an object

• Inertia

• Balanced Force

• Push

• Unbalanced Force

Forces are measured in:

• Inertia

• Grams

• Tons

• Newtons

An unequal push/pull on an object that causes a change in motion:

• Unbalanced Force

• Push

• Balanced Force

• Inertia

The tendency for an object's motion to remain unchanged:

• Newton's 3rd Law

• Unbalanced Force

• Gravity

• Inertia

Speed plus direction:

• Inertia

• Velocity

• Acceleration

• Force

A change in speed or direction; a change in velocity

• Acceleration

• Force

• Inertia

• Net force

The sum (total) of all forces acting on an object:

• Unbalanced Force

• Balanced Force

• Newtons

• Net Force

The greater the mass of an object, the more force it will take to accelerate the object.

• Newton's 1st Law of Motion

• Newton's 2nd Law of Motion

• Newton's 3rd Law of Motion

What is the formula for force?

• F=M/A
• F=A/M
• F=M*A
• F=M*F
