Force, Motion, & Machine Review

Front

What is the value for gravity on Earth?

Back

9.8 m/s²

Front

What does a constant speed graph look like?

Back

A straight line with a constant slope.

Front

What is the difference between weight and mass?

Back

Weight is a function of gravity; mass is the amount of matter in an object.

Front

How can you identify an object moving at a slower speed on a graph?

Back

It is represented by a line with a gentler slope compared to faster objects.

Front

During which interval is an object speeding up?

Back

When the slope of the graph is increasing.

Front

What is force?

Back

A push or pull on an object that can cause it to accelerate.

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 acceleration?

Back

The rate of change of velocity of an object.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is kinetic energy?

Back

The energy an object has due to its motion, calculated as KE = 1/2 mv².
