Understanding Motion and Acceleration

What distinguishes velocity from speed?

• Velocity is always greater than speed.

• Speed includes direction, while velocity does not.

• Velocity includes direction, while speed does not.

• Speed is always greater than velocity.

What happens to an object's velocity when it is in free fall?

• It decreases due to air resistance.

• It decreases due to gravity.

• It remains constant.

• It increases due to gravity.

What is the acceleration due to gravity on Earth?

• 9.8 m/s² upwards

• 9.8 m/s² downwards

• 0 m/s²

• 19.6 m/s² downwards

How can you determine the missing values in a motion table?

• By measuring the area under the curve.

• By guessing based on previous values.

• By using the slope of the graph.

• By applying the correct equations.

What does the area under a velocity-time graph represent?

• The object's displacement.

• The object's acceleration.

• The object's speed.

• The object's mass.
