Physics - Unit 1.1 Linear Motion Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What does it mean for an object to be 'speeding up'?

Back

An object is 'speeding up' when its velocity is increasing over time, meaning it is gaining speed.

Front

What does it mean for an object to be moving at 'constant speed'?

Back

An object is moving at 'constant speed' when it covers equal distances in equal intervals of time, regardless of the direction.

Front

What is instantaneous velocity?

Back

Instantaneous velocity is the velocity of an object at a specific moment in time.

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

How do you calculate average speed?

Back

Average speed can be calculated using the formula: Average Speed = Total Distance / Total Time.

Front

What is the formula for calculating acceleration?

Back

The formula for calculating acceleration is: a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

Front

What does a negative acceleration indicate?

Back

Negative acceleration, also known as deceleration, indicates that an object is slowing down.

Front

What is the significance of a velocity-time graph?

Back

A velocity-time graph shows how the velocity of an object changes over time, allowing for the analysis of acceleration and motion.

Front

What does it mean if the velocity-time graph is a straight line?

Back

If the velocity-time graph is a straight line, it indicates that the object is moving at a constant velocity.
