Physics Midterm Review

Front

What is the formula to calculate final velocity when starting from rest?

Back

Final Velocity (v) = Initial Velocity (u) + Acceleration (a) × Time (t). For an object starting from rest, u = 0, so v = a × t.

Front

How do you calculate the time taken to cover a distance at a constant speed?

Back

Time (t) = Distance (d) / Speed (s).

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

How do you find the y-component of a vector given its magnitude and angle?

Back

Use the formula: y-component = Magnitude × sin(Angle).

Front

What is mass?

Back

Mass is the amount of matter in an object, typically measured in kilograms (kg).

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

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 formula for calculating force?

Back

Force (F) = Mass (m) × Acceleration (a).

Front

What is the relationship between distance, speed, and time?

Back

Distance = Speed × Time.

Front

What is the significance of the angle in vector components?

Back

The angle determines how the vector is split into its x and y components, affecting its direction and magnitude.
