Physics Quiz: Uniformly Accelerated Motion

What is acceleration?

• Rate of change of time with respect to velocity

• Rate of change of displacement with respect to time

• Rate of change of speed with respect to time

• Rate of change of velocity with respect to time

What is instantaneous acceleration?

• Average acceleration over a period of time

• Acceleration at a specific instant in time

• Acceleration due to gravity

• Acceleration that changes continuously

Which equation represents displacement in uniformly accelerated motion?

• v² = u² + 2as

• v = u + at

• a = dv/dt

• s = ut + 0.5at^2

What type of graph represents velocity-time in uniformly accelerated motion?

• Parabolic curve

• Horizontal line

• Straight line

• Vertical line

What is the acceleration due to gravity?

• 1 m/s²

• 9.8 m/s²

• 0 m/s²

• -9.8 m/s²

What is terminal velocity?

• Velocity at the highest point of motion

• Velocity at rest

• Initial velocity of an object

• Maximum velocity when drag force equals gravitational force

What is the equation for terminal velocity?

• v_t = √(2mg/ρAC_d)

• s = ut + 0.5at^2

• v = u + at

• v² = u² + 2as

What type of motion is vertical motion?

• Uniform motion

• Special case of uniformly accelerated motion

• Random motion

• Circular motion

What does the velocity-squared equation represent?

• v² = u² + 2as

• a = dv/dt

• s = ut + 0.5at^2

• v = u + at
