Forces
What is force?
Force is a push or pull that acts on an object.
What is contact force?
Is a force that requires two pieces of matter to touch
What is non-contact force?
a force that acts at a distance
What Chapter is the new Fortnite season?
Chapter 6 season 1
What is Newtons first law?
His first law of motion says that an object will stay in motion unless a net force acts on the object
What is the unit for measuring force?
Newtons
True or False:
One kind of contact force is friction
true
What are some examples of non-contact force?
Gravity, electric forces, magnetic forces
What will Ms. Sanchez do during the winter break?
Fortnite
Define inertia?
Inertia is the tendency of an object to resist any change in motion.
True or False:
A force can make an object slow down or stop
True
because friction is a contact force that can cause an object to slow down or stop by making it harder for one surface to move past another.
What is friction?
Friction is the force that results when two materials rub against each other or when their contact prevents sliding.
What is gravity?
is the force of attraction between any two objects.
What is Ms. Sanchez cat name?
Yumi
What is Newtons 2nd law?
His 2nd law describes how acceleration, mass, and force are related
What causes an object to change direction?
Force
What are some factors that affect the amount of friction between two objects?
Shape, speed, texture, or weight
In what direction does gravity pull you?
Gravity pulls you toward the center of the Earth.
True or False
A large boat will experience more acceleration because it has more mass.
False
A large boat will experience less acceleration because it has more mass.
How can pedaling affect the motion of your bike?
You speed up
What types of surfaces will result with less friction?
Smooth, slippery, icy, or wet surfaces.
What kinds of magnetic poles attract each other? What kind of magnetic poles repel each other?
North pole attracts to south pole magnets. The north pole of two magnets will repel as well as the south poles.
What is Newton's 3rd law?
His 3rd law states that when one object exerts force on a second object, the second object exerts a force on the first. These forces are equal in strength and opposite in direction.
