Magnetism
Gravity
What is the net force?
3 N
3 N, right
17 N, right
3 N, left
When the sum of forces (net force) is equal to zero, we call this situation ...
Balanced force
Unbalanced force
Based on the field lines, will these magnets be attracted or repelled?
Attracted
Repelled
The subatomic particles responsible for electricity and magnetism are called...
electrons
neutrons
protons
photons
Rougher (opposite of smooth) surfaces have ...
More friction
Less friction
Mass is the amount of matter in an object.
True
False
What is the unit for weight? (TIP: Weight is a force)
kilogram (kg)
newton (N)
What's the difference between speed and velocity
Speed is a scalar quantity (just a number).
While velocity also implies a direction (number + direction)
They are the same thing
The velocity is just a number, while speed informs the direction
_______ pulls objects toward Earth’s surface
friction
effort force
gravity
resistance force
Newton's second law states.....
If there is more mass then there is more acceleration
An object at rest wants to be in motion
Force = Mass x Acceleration
The force exerted on an object is not related to mass or acceleration
What is inertia?
An object that is accelerating
Gravitational force
An objects tendency to stay at rest or in motion
An unbalanced force
Newton's third law states.......
For each action there is a larger reaction associated with it.
None of these choices
For each action there is an equal and opposite reaction.
For each action there is a smaller reaction associated with it.
When forces are going in the opposite direction of each other, what should you do to find the NET force?
Subtract
Add
Multiply
If both forces are going in the same direction you should______ those forces
Add
Subtract
Divide
Multiply
If there are two forces vectors going in the same direction how would you find the net force?
Which one is balanced? (Net Force = 0)
According to Newton's second law, if you increase the force applied to an object :
it accelerates more (speeds up)
it decelerates (slows down)
Plastic
What happens when two north poles (equal poles) of a magnet are placed together?
They Repel
They Attract
Opposite poles will attract each other.
True
False
Which of the following objects cannot be moved by a magnet?
A metal paper clip
An iron nail
A wood toothpick
