1D Kinematics Flashcard

Front

Describe the motion in segment C.

Back

Speeding up; Negative direction.

Front

What is the velocity of an object at the highest point when thrown straight up at 60 m/s?

Back

0 m/s.

Front

A car traveling at 21.0 m/s slows to a stop in 5.00 s. How far does it travel before stopping?

Back

52.5 m.

Front

What is the acceleration of an object moving at constant velocity?

Back

0 m/s².

Front

A dog running with an initial speed of 7.5 m/s comes to a stop in 15 seconds. What is the dog's acceleration?

Back

-0.5 m/s².

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating distance when acceleration is constant?

Back

Distance = Initial Velocity × Time + 0.5 × Acceleration × Time².

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the significance of the highest point in a projectile's motion?

Back

At the highest point, the velocity of the object is 0 m/s before it starts descending.
