Study of motion with reference to the force which causes the motion is:

• Statics

• Dynamics

• Kinetics

• Kinematics

An impulse causes:

• The object’s momentum to change

• The object’s momentum to decrease

• The object’s momentum to increase

• The object’s momentum to remain constant or be conserved

Momentum is a property related the object’s____.

• Motion and mass

• Mass and acceleration

• Motion and velocity

• Weight and velocity

Centrifugal force is____.

• Directly proportional to the radius of the curvature

• Directly proportional to the square of the tangential velocity

• Inversely proportional to the square of the tangential velocity

• Directly proportional to the square of the weight of the object

A measure of the resistance of a body it offers to any change in its angular velocity, determined by the mass and distribution of its mass about the axis of rotation is knows as:

• Moment of inertia

• Friction

• Torsion

• Angular acceleration

Momentum is the product of mass and:

• Acceleration

• Velocity

• Force

• Time

The moment of inertia of a plane figure ____.

• Increases as distance of the axis moves farther from the centroid

• Is maximum at the centroidal axis

• Is zero at the centroidal axis

• Decreases as the distance of the axis moves farther from the centroid

The maximize the horizontal range of the projectile, which of the following applies?

• Maximize velocity

• Maximize the angle of elevation and velocity

• Maximize the angle of elevation

• The tangent function of the angle of trajectory must be equal to 1

Moment of inertia of any plane figure is expressed in units of length to the

• First power

• Second power

• Fourth power

A branch of physical science which deals with state of rest or motion of bodies under the action of forces.

• Mechanics
