Force and Motion Review

Front

What information does Lola need to measure her average speed when biking?

Back

Lola needs to gather the distance traveled and total time traveled.

Front

What describes the motion of cars with constant and variable speeds?

Back

Cars 1 and 3 have variable speeds, whereas Car 2 has a constant speed.

Front

What can cause a moving object to change direction?

Back

Force can cause a moving object to change direction.

Front

How can we describe an object's motion if it is moving with constant velocity?

Back

The object is moving with constant velocity.

Front

Why does a book stay still on a desk?

Back

The forces acting on the book are balanced.

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time.

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 is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.
