24-25 Semester Check Units 1-4

Front

What is distance in physics?

Back

Distance is the total path length traveled by an object, regardless of direction.

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 with respect to time.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object.

Front

What role does friction play in motion?

Back

Friction is a force that opposes the motion of an object, acting to slow it down or stop it.

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line that shows equal distance covered over equal time intervals.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is the formula for acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the significance of a flat line on a distance-time graph?

Back

A flat line on a distance-time graph indicates that the object is not moving.
