Curvilinear Motion

The path of a ball that is thrown upwards is called

• A straight line

• A parabolic curve

• A circular path

• An elliptical path

In a curvilinear motion, the acceleration must always act:

• tangent to the curvature

• inwards of the curvature

• in the direction of the motion

In a curvilinear motion, the velocity must always be:

• tangent to the curvature

• inwards of the curvature

• in the direction of the motion

Which is the following is the constant downward acceleration used in the study of curvilinear motion using (x,y) analysis

• Weight

• Friction

• Mass

• Gravity

As the particle moves upward, the velocity

• increases

• decreases

• remain constant

In a projectile motion, the particle will _____________ at its maximum height.

• stop momentarily

• accelerate

• decelerate

• disappear

The horizontal velocity is always constant in a projectile motion

• True

• False
