Motion and Forces Overview

Front

What does a graph showing a straight line indicate about motion?

Back

Constant Speed

Front

What is the net force when all forces acting on an object cancel each other out?

Back

0 N

Front

If an object is experiencing a net force of 400 N downward, what is the direction of the net force?

Back

400 N Down

Front

What does a horizontal line on a motion graph represent?

Back

Body at rest

Front

What is defined as a change in speed, a change in direction, or both?

Back

Acceleration

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / 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 inertia?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the object's motion.
