What is attract?
A force that requires two pieces of matter to touch.
What is contact force?
Name 3 ways that an object can accelerate.
What are speed up, slow down, or change direction?
The greater the force applied, the greater the change in motion for a given mass.
What is Newton's 2nd Law of Motion?
When a push or pull acts on an object.
What is force?
A force that results when two materials rub against each other or when their contact prevents sliding.
What is friction?
The tendency of an object to resist any change in motion.
What is inertia?

What are newtons?
Name two factors that affect the amount of friction between two objects.
What is shape, speed, texture, or weight?

What are friction and air resistance?
Name 2 things a force can do when an object is already moving.
What are speed up, slow down, or change direction?
A force that acts at a distance.
What is a non-contact force?
The rate at which the speed or direction of motion of an object changes over time.
What is acceleration?
For every action there is an equal and opposite reaction.
What is Newton's 3rd Law of Motion?
The way pedaling affects the motion of a bike.
What is speeding up?
A force of attraction between any two objects.
What is gravity?
The force that results when two materials rub against each other or when their contact prevents sliding.
