Force
Newton's Laws
Newton's First Law
Newton's Third Law
100

a push or pull that one body/object exerts on another

force

100

For every action there is an equal and opposite reaction force

Newton's third law of motion

100

what force causes an object resist a change in motion and remain unchanged?

Inertia

100

Give one example of Newton's third law of motion

 (teacher will decide whether team get the points)

200

the overall sum of all the forces acting on an object

net force

200

An object at rest will remain at rest and an object in motion will continue moving at with the same ______________ and ______________ unless acted on by an unbalanced force

SPEED and DIRECTION (also, Newton's first law ^-^)

200

Give one example of Newton's first law of motion

(teacher will decide if team gets the points)

200

What force is considered the "reaction" in this example.

Action: Person's feet pushes off the wall

Reaction: Wall pushes back on person's feet

300

What happens if the net force acting on an object is zero

The object will not move/change

300

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional its mass

Newton's 2nd law

300

An object that is still will only change if acted upon by an _______________.

unbalanced force

300

Consider the flying motion of birds. A bird flies by using its wings. The wings of a bird push air downwards, causing the bird to fly upwards. What is the action in this example?

the bird pushing air downwards

400

Two/more forces that are equal in size and acting in opposite direction

Balanced force

400

What are all of Newton's Laws Related to?

Motion

400

An object with a lot of inertia is likely to do what

Resist change

400

Newton's third law of motion states that forces always act in __________.

pairs.

500

How do you calculate Net Force

You find the overall sum of all forces acting on the object. (ADD the forces in the SAME direction...SUBTRACT the forces in OPPOSITE directions).

500

The acceleration of an object is ______________ proportional its mass.

INVERSELY
500

Newton's first law is also known as __________________

The law of inertia

500

Newton's third law is also known as the law of _______________.

Action-Reaction
