What is force?
A push or pull upon an object resulting from the object's interaction with another object.
What is free fall?
Any motion of an object where gravity is the only force acting upon it.
What is the value and variable (letter) we use to represent gravity?
9.8 m/s2 & g or a
What is an example of something that is NOT force?
.
What is balanced & unbalanced force?
Balanced force is when the net force is 0N. Unbalanced force is when the net force is anything BESIDES 0N
What is terminal velocity?
The constant speed that a freely falling object eventually reaches when air resistance prevents further acceleration.
What is the difference between mass and weight?
Mass is the amount of matter in a material. Weight is a measure of how the force of gravity acts upon that mass.
What do you use to measure force?
Force gauge, Newton-metre, spring balance, etc.
What is friction?
Opposing motion between two surfaces
What is kinetic friction?
A force that acts between moving surfaces
What is static friction?
The frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome.
If a ball is dropped off a building, what will the velocity be after 6 seconds, ignoring air resistance?
58.8m/s2
If a ball is dropped off of a building and and falls for 7 seconds, what is the displacement (how far did it travel)?
240.1m
What is the net force?
1398N
