Multiply the magnitudes of the vectors

Subtract the magnitudes of the vectors

Add the magnitudes of the vectors together

What is Newton's 1st Law?

An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

An object at rest will start moving on its own without any external force

An object in motion will eventually come to a stop without any force acting on it

An object in motion will change its speed and direction without any external force

What is Newton's 3rd Law?

For every action, there is an equal and opposite reaction.

For every action, there is an unequal and opposite reaction.

Newton's 3rd Law is about the force of gravity.

Newton's 3rd Law states that objects at rest tend to stay at rest.

How do you solve for weight and give the proper Sl units?

Weight can be solved using the formula: F = mass x acceleration due to gravity. The proper SI unit for weight is Newton (N).

Weight can be solved using the formula: F = mass / acceleration due to gravity. The proper SI unit for weight is pound (lb).

Weight can be solved using the formula: F = mass x velocity. The proper SI unit for weight is kilogram (kg).

Weight can be solved using the formula: F = mass x acceleration due to gravity. The proper SI unit for weight is meter (m).

According to Newton's third law, if you push gently on something, it will push...

back on you with an equal force

away from you with a greater force

What is friction? Which direction does it move in?

Opposite direction of the motion

What are action-reaction pairs?

Equal in magnitude and opposite in direction

Unequal in magnitude and opposite in direction

Equal in magnitude and random in direction

Equal in magnitude and same in direction

Units and variable for time

seconds, minutes, hours, days, weeks, months, years, t

apples, bananas, oranges, grapes

Units and variable for force

Newtons (N), F (force), m (mass), a (acceleration)

Watts (W), P (power), θ (angle)

Pounds (lbs), G (gravity), d (distance)

Kilograms (kg), V (velocity), t (time)

Meters, kilometers, miles, etc.

What happens if 2 objects of different masses fall in a vacuum? In a tube with air resistance?

Both objects will fall at the same rate in a vacuum, but the heavier object will fall faster in a tube with air resistance.

The lighter object will fall faster in a vacuum, but the heavier object will fall faster in a tube with air resistance.

Both objects will fall at the same rate in a tube with air resistance.

Both objects will fall at different rates in a vacuum, with the heavier object falling slower.
