Dynamics-Curvilinear Motion

Curvilinear Motion

The motion of an object moving in a curved path

Curvilinear Motion

This describes the motion of a moving particle that conforms to a known or fixed curve

Change

In curvilinear motion, the displacement vector will -- both in magnitude and inclination

Velocity acceleration

Although -- is always directed tangent to the curved path of the motion, the -- is not tangent to the path

Projectile

It is an object upon which the only force acting is gravity

Projectile

Any object thrown into space upon which the only acting force is gravity

gravity

By definition, a projectile has a single force that acts upon it -

True

If there were any other force acting upon an object, then that object would not be a projectile. True or False

Inertia

A projectile is any object that one projected or dropped continues in motion by its own -- and influenced only by the downward force of gravity

Air resistance

It decreases the horizontal component of a projectile

True

The only force acting on a projectile is its own weight. True or False

False (zero not maximum)

At the top most point of flight, the value of Vy will be at maximum. True or False

Tangents and Normal

Most useful components of acceleration are those which are -- and -- to the path

magnitude and direction

These components denote the rate of change of -- and -- of velocity
