Distance and Displacement / Motion Review

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight line from the starting point to the endpoint, including direction.

Front

Define constant speed.

Back

Constant speed means an object covers equal distances in equal intervals of time, regardless of how small those intervals are.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point over time.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is a vector quantity?

Back

A vector quantity has both magnitude and direction, such as displacement and velocity.

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude and no direction, such as distance and speed.

Front

If Sara walks 3 meters east and then 4 meters north, what is her displacement?

Back

Her displacement is 5 meters northeast, calculated using the Pythagorean theorem.

Front

What happens to the speed of an object if it accelerates?

Back

If an object accelerates, its speed increases over time.

Front

What is the formula for calculating distance?

Back

Distance = Speed × Time.

Front

What does it mean for an object to decelerate?

Back

Deceleration means the object is slowing down, resulting in a decrease in speed.
