Forces linear motion, fluid and angular motion

Newtons law of inertia states

• A body will continue in a non parabolic flight path until acted on by air resistance

• A body continues in a state of rest or uniform velocity unless acted upon by an external force

• A body continues in a uniform velocity indefinitely

• A body will continue in a parabolic flight path until acted on by air resistance

Define parabolic flight path

Define non parabolic flight path

Define moment of inertia

What are the forces acting on a projectile in flight?

Name three

What is the law of acceleration

Define linear motion

What is the difference between scalar and vector quantities?

velocity is

• the rate of change of displacement, the speed of a body in a given direction

• the rate of spin

• how parabolic the flight path is

• the rate of change of speed over time

Define displacement
