Mid-term Exam Review

Front

What kind of bridge is a Suspension bridge?

Back

A Suspension bridge is a type of bridge where the deck (the load-bearing portion) is hung below suspension cables on tall towers.

Front

What does the slope of a distance vs. time graph represent?

Back

The slope of a distance vs. time graph represents the speed of the object.

Front

Calculate the distance traveled if a person walks 3 miles north and then 2 miles east.

Back

The total distance traveled is 5 miles.

Front

What is Kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What kind of bridge is a Truss bridge?

Back

A Truss bridge is a type of bridge that uses a truss, which is a structure of connected elements forming triangular units.

Front

Define 'Distance' in physics.

Back

Distance is a scalar quantity that represents the total path length traveled by an object.

Front

Define 'Speed' in physics.

Back

Speed is a scalar quantity that measures how fast an object is moving, calculated as distance divided by time.

Front

What is the formula for calculating Kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is a Beam bridge?

Back

A Beam bridge is a simple type of bridge that consists of horizontal beams supported at each end.

Front

What is the difference between Distance and Displacement?

Back

Distance is the total path length traveled, while Displacement is the shortest straight-line distance from the initial to the final position.
