Force, work, and motion

Front

What is Newton's 1st 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 the formula for calculating work?

Back

Work = Force x Distance (W = F x d) where work is measured in Joules.

Front

What is the unit of work?

Back

The unit of work is Joules.

Front

What is the definition of force?

Back

A force is a push or pull on an object that can cause it to change its velocity.

Front

What is the unit used to measure force?

Back

The unit used to measure force is Newtons.

Front

What is Newton's 2nd 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 the definition of mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

Front

What is Newton's 3rd Law of Motion?

Back

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.
