Physics Semester Review

Front

What is the position of an object at t = 70 seconds if it is at rest?

Back

0 m

Front

Which graph correctly shows the vertical velocity of an object thrown straight up and returning to the ground?

Back

Graph 2

Front

If you shoot an arrow horizontally and drop a ball from the same height, which lands first?

Back

They land at the same time.

Front

In a position vs time graph, what does a steeper graph indicate?

Back

The object is moving faster.

Front

What does the slope of a velocity vs time graph represent?

Back

The acceleration of the object.

Front

Define acceleration in the context of physics.

Back

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

Front

What is the formula for calculating acceleration?

Back

a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

Front

Explain the concept of displacement.

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does a flat line on a velocity vs time graph indicate?

Back

The object is moving at a constant velocity.
