Newton's Laws of Motion

Front

What is the force caused by objects rubbing together?

Back

Friction is the force that opposes the motion of two surfaces in contact.

Front

What force pulls objects down towards the center of the Earth?

Back

Gravity is the force that attracts two bodies towards each other, pulling objects towards the center of the Earth.

Front

What causes a rocket to launch?

Back

A rocket launches because of an opposite reaction, as described by Newton's Third Law of Motion.

Front

What type of force is needed to move objects of larger mass?

Back

More force is needed to move objects of larger mass due to their inertia.

Front

What force is caused by air and slows things down?

Back

Air Resistance is the force that opposes the motion of an object through the air.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

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 Newton's Third Law of Motion?

Back

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

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 gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.
