## 24 terms

a push or a pull

### mass

the amount of matter in an object

### acceleration

the change in velocity in a given amount of time

### inertia

name for resistance to a change in motion. An object at rest tends to stay at rest, and a moving object tends to keep movin in a straight line until it is affected by a force.

### friction

the force exerted when two surfaces rub together

### fluid friction

force exerted on an object due to a liquid or a gas

### rolling friction

force exerted by rolling objects

### sliding friction

force exerted when two objects slide past one another

### centripetal force

the inward force on a body moving in a curved path around another body

### Newton's 1st Law of Motion

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

### Newton's 2nd Law of Motion

Force is the product of mass and acceleration

### Newton's 3rd Law of Motion

For every action there is an equal and opposite reaction

### What is the first law of Motion called

the law of inertia

### elastic force

the force caused by tension or compression

### balanced forces

equal forces acting on an object in opposite directions

### unbalanced forces

the forces acting on a object that cause a change in velocity; making the object speed up, slow down, or change direction

### net force

the overall force on an object when all the individual forces acting on an object are added together.

### weight

is the measure of gravitional force on a mass

### gravity

A force of attraction between objects that is due to their masses

### air resistance

frictional force air exerts on a moving object; acts opposite in direction to the object's motion

### speed

the amount of distance in a given amount of time

### velocity

speed in a given direction

### projectile

an object that is thrown

f = m x a
