Force & Motion and Newton's Laws

Front

What is the unit to MEASURE force?

Back

Newton

Front

If a 10 kilogram object accelerates suddenly at 15 m/s², how much force was applied to the object?

Back

150 Newtons

Front

If two boys are pulling with the same amount of force, what will happen?

Back

They will not move at all.

Front

Speed is equal to _____________.

Back

Distance/Time

Front

A measure of how fast something moves over a certain distance is ________________.

Back

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 unless acted upon by a net external force.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a)

Front

What does acceleration measure?

Back

Acceleration measures the rate of change of velocity of an object.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
