Physics Final Review Part 2

Front

What is Newton's 1st Law of Motion?

Back

An object with a constant velocity will maintain that velocity unless acted on by an unbalanced outside force.

Front

What is the definition of Work in physics?

Back

Work is done when a force causes an object to move. If there is no movement, no work is done.

Front

Which action requires no Work?

Back

Carrying a 25 kg backpack home from school requires no work because the backpack is not being lifted or moved in the direction of the force.

Front

What is the formula to calculate speed?

Back

Speed = distance/time.

Front

What is velocity?

Back

Velocity is speed in a specific direction.

Front

What does the slope of a speed-time graph indicate?

Back

The slope of a speed-time graph indicates acceleration.

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 acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (final velocity - initial velocity) / time.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
