Newton's Laws of Motion

Front

What is the definition of friction in physics?

Back

Friction is the resistance that occurs when a surface of an object moves over another surface.

Front

What does Newton's 3rd Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

Provide an example of Newton's First Law of Motion.

Back

A soccer ball remains motionless until it is kicked by a player.

Front

What happens to two objects when they collide according to Newton's laws?

Back

They hit each other with the same force in opposite directions.

Front

What causes a ball rolling across a rug to slow down?

Back

Friction resists the ball's forward motion.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is inertia?

Back

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

Front

How does mass affect the force required to accelerate an object?

Back

A greater mass requires a greater force to achieve the same acceleration.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F=ma).

Front

What is an example of balanced forces?

Back

A book resting on a table experiences balanced forces: the weight of the book downward and the normal force of the table upward.
