What is the study of forces and the motion they cause Ans✓✓✓Kinetics
What is a quantitative measure of the amount of inertia an object has
Ans✓✓✓mass
Is mass a scalar or a vector? Why? Ans✓✓✓Scalar it only has
magnitude
What is the natural tendency of an object to remain at rest or in motion
at a constant speed in a straight line? Ans✓✓✓inertia
What law states: a body at rest stays at rest and a body in motion stays in
motion along a straight line unless acted upon by a net force. Ans✓✓✓I
law of inertia
What law states: acceleration experienced by a body is directly
proportional to the net force and inversely proportional to it's mass and it
occurs in the direction of the force? Ans✓✓✓II law of acceleration
What is the equation for Newton's II law? Ans✓✓✓ΣF=ma

reaction? Ans✓✓✓III Law of reacton
What force accelerates the ground in the direction of the force?
Ans✓✓✓applied
What force is equal in magnitude and opposite in direction to the applied
force? Ans✓✓✓reaction
Which force accelerates your center of mass? Ans✓✓✓reaction force
When drawing a FBD should you always assume the directions of the
contact forces are positive or negative? Ans✓✓✓positive
What is the product of the object's mass and velocity? Ans✓✓✓Linear
momentum
What is a vector that points in the same direction of velocity with units
of kg*m/s? Ans✓✓✓linear momentum
What states that the total linear momentum of a system of objects is
constant if the net external force acting on the system is zero?
Ans✓✓✓Principle of Conservation of linear mometum
