IXPhysics Quiz Chap 2,3,& 4 (AKUEB)

A body at rest relative to its surroundings:

• Is not moving.

• Moves with constant velocity.

• Has unchanging position.

• Accelerates.

Which isn't translational motion?

• Linear

• Rotatory

• Random

• Circular

Displacement is:

• Scalar.

• Shortest distance.

• Always = distance.

• Total path length.

Car travels 10km E, then 10km W. Displacement:

• 20km

• 10km

• 0km

• -10km

Speed is:

• Rate of displacement change.

• Rate of velocity change.

• Distance/time.

• Displacement/time.

Velocity is:

• Scalar.

• Same as speed.

• Displacement/time.

• Distance/time.

Constant velocity means:

• Zero acceleration.

• Increasing acceleration.

• Decreasing acceleration.

• Non-uniform acceleration.

Distance-time graph slope:

• Acceleration.

• Velocity.

• Displacement.

• Distance.

Speed-time graph area:

• Acceleration.

• Velocity.

• Displacement.

• Distance.

Horizontal line on speed-time graph:

• Constant velocity.

• Constant acceleration.

• Zero velocity.

• Decreasing velocity.
