What are the appropriate units to describe acceleration?

Back

m/s²

Front

Back

Newtons

Front

If a skateboarder hits a rock and stops while the person continues moving, which law explains this?

Back

The Law of Inertia (1st law)

Front

What is the net force when 8 N is applied to the left and 4 N to the right? Is this balanced?

Back

4 N Left; No

Front

What is the equal but opposite reaction when you hit a wall with a stick?

Back

The wall pushes against the stick.

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 formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is inertia?

Back

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