CH 2 Quiz part I (Kinematics and Projectile Motion)

Kinematics is the study of:

• The causes of motion

• The forces acting on objects

• The description of motion

• The energy involved in motion

Displacement is a vector quantity that refers to:

• The total distance traveled

• The change in position

• The rate of change of position

• The acceleration of an object

The slope of a position-time graph represents:

• Displacement

• Velocity

• Acceleration

• Distance

The slope of a velocity-time graph represents:

• Displacement

• Velocity

• Acceleration

• Distance

For motion with constant acceleration, the velocity-time graph is a:

• Straight line

• Parabola

• Hyperbola

• Circle

The area under a velocity-time graph represents:

• Displacement

• Velocity

• Acceleration

• Distance

In projectile motion, the horizontal component of velocity:

• Remains constant

• Increases with time

• Decreases with time

• Varies sinusoidally with time

The maximum height reached by a projectile depends on:

• Initial velocity only

• Angle of projection only

• Both initial velocity and angle of projection

• Neither initial velocity nor angle of projection

The time of flight of a projectile is maximum when the angle of projection is:

• 0°

• 30°

• 45°

• 90°

The horizontal range of a projectile is maximum when the angle of projection is:

• 0°

• 30°

• 45°

• 90°
