Newton's Laws

Front

What is the force applied to all objects on Earth?

Back

Gravity

Front

What is the difference between mass and weight?

Back

Mass is how much matter is in an object, and weight is the gravitational pull on that object.

Front

Which of the following is an example of Velocity? (Think...Velocity has to have a speed and a _______.)

Back

25 m/s East

Front

What do each of the letters in F=ma correctly represent?

Back

Force, Mass, Acceleration

Front

A 20 kg bike accelerates at 10 m/s². What was the net force? (Use FMA Triangle and solve for force)

Back

200 Newtons

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 the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is the formula to calculate weight?

Back

Weight = mass × gravitational acceleration (W = mg).
