TEST: Force & Laws of Motion

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia. This means heavier objects are harder to start or stop moving.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that 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 Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It can be classified into static, sliding, rolling, and fluid friction.

Front

What type of friction does a hockey puck experience when sliding on ice?

Back

The hockey puck experiences sliding friction when it is in play.

Front

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

Back

According to Newton's 2nd Law, the force acting on an object is equal to the mass of the object multiplied by its acceleration (F=ma).

Front

What is an example of Newton's 1st Law in everyday life?

Back

An example is when a car suddenly stops, and passengers lurch forward due to inertia.

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, affecting the motion of objects, especially those in free fall.
