_________occurs when two objects collide and the momentum and kinetic energy is conserved

what is the property of matter by which it continues in its exist in state of rest or uniform motion

what equation is given through Newton's 2nd law

which are not one of the four types of mechanical force?

what do we call a push or pull on a system

if one force overpowers another movement is the the result and we say the forces are

gravity cause objects to

what is the process of losing thermal energy? and gaining thermal energy?

what are the three subatomic particles?

what measures the positions, speed, or velocity, and acceleration of objects

is kinetic energy mechanical energy?

an imaginary line marked off in distance units

objects that fall due to gravity alone with no other force acting on them are in

what is the velocity formula?

what are the units for acceleration?

what is the transmission of energy through matter by particle oscillations ?

What is mechanics?

when the observational point of view is NOT moving at a constant speed or direction

An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.

If there is an equal force in opposite directions, then the overall force is

what is the property of moving objects which is determines the amount of force needed to change their motion

what is the resistance that one surface or object encounters when moving over another

what is anything that is not within the boundary we have created called?

a positive scalar quantity with not direction associated with it

what is the acceleration formula?

_________ causes the colliding objects to be slightly deformed and lose some kinetic energy

what is the first law of thermodynamics also known as

the process of smashing nuclei together to form a larger one

what field force surrounds anything made of matter?

What is produced in a system or material affected by an elastic force?

the process of splitting the nucleus of an atom into smaller pieces

what is the force exerted on objects that are not touching?

what is also known as mechanical energy, stored energy, or energy caused by position?

_________occurs when colliding objects stick together after the collision and kinetic energy is not conserved

when you assume a point of view is stationary, even though it is actually moving is

a vector quantity that involves distance but also includes a direction

Energy is the ablity to

A reference frame that is NOT stationary and in which speed and direction are changing

which is not a field force?

what is the energy of motion

how do you find change in speed?

what is the value of gravitational acceleration?

what is the boundary that clearly defines the limits of an object you are studying

All matter consists of small particles that are

for every action there is an equal and opposite reaction

All matter consists of smaller particles called

Atoms are bonded together and this energy is stored in these bonds is

who realized that motion of objects is a result of pushes and pulls

as potential energy increases, what happens to kinetic energy?

because of the air molecules in the way, falling objects experience_____________ which slows them down
