Mechanical Energy Midpoint Review

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a stretched rubber band or an object at height.

Front

What is the relationship between speed and kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point over time.

Front

What is a constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time, without changing its speed.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

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.
