Newton's Laws, Simple Machines, Speed

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 with the same speed and in the same direction unless acted upon by an unbalanced 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

Define 'force'.

Back

Any push or pull on an object.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is a simple machine?

Back

A device that makes work easier by allowing us to push or pull over increased distances.

Front

Identify the six types of simple machines.

Back

Lever, Inclined Plane, Wedge, Screw, Pulley, Wheel and Axle.

Front

What is a pulley?

Back

A simple machine that consists of a wheel on an axle or shaft that is designed to support movement and change the direction of force.

Front

What is the net force?

Back

The overall force acting on an object when all the individual forces are combined.
