weight

friction

free fall

gravity

### force that causes objects to move in a circular motion

centripetal force

air resistance

### for every action there is an equal and opposite reaction

action/reaction forces

Mass

### the total momentum of any group of objects remains the same or is conserved unless acted upon by an outside force

conservation of momentum

### causes air borne objects to follow a curved path because they move forward while gravity brings them down

projectile motion

net force

balanced forces

### cause objects to start stop or change direction

unbalanced forces

fluid friction

rolling friction

sliding friction

### an object at rest will remain at restunless acted upon by an unbalanced force and an object moving at a constant velocity will continue moving at a constant velocit, unless it is acted upon by an unbalanced force another name is Law of Inertia

Newton's first law of motion

### An objects mass and the amount of net force acting on the object contribute to how much an object can accelerateIe

Newton's second law of motion

### one object exerts a force on another object then the second object exerts an equal force in the opposite direction of the first object

Newton's third law of motion
