TREAT Force and Laws of Motion

Front

When two equal forces act in opposite directions on an object, they are called ______________________.

Back

balanced force

Front

The law that states that an object will remain at rest or in uniform motion unless acted upon by an unbalanced force is known as ______________________.

Back

Law of Inertia - 1st Law

Front

The law that states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass is known as ______________________.

Back

Law of Acceleration - 2nd Law

Front

When an unbalanced force acts on an object, the force ______________________.

Back

changes the motion of the object

Front

The law that states that for every action, there is an equal and opposite reaction is known as ______________________.

Back

3rd Law of Motion

Front

If a man pushes a chair to the right with 4N of force and his wife pushes the chair to the left with 4N of force, what is the net force?

Back

0N

Front

The force that opposes the motion of an object is called ______________________.

Back

frictional force

Front

The force of attraction between two masses is known as ______________________.

Back

gravitational force

Front

An object in motion will stay in motion unless acted upon by an unbalanced force is a statement of which law?

Back

1st Law of Motion

Front

The acceleration of an object is calculated using the formula ______________________.

Back

F = ma (Force = mass x acceleration)
