Physics Unit 2 Blitz

Front

What does Newton's first law of motion state?

Back

Objects at rest remain at rest, and objects in motion continue in motion at the same velocity, unless acted upon by an outside force.

Front

What is the formula to calculate force?

Back

F = m * a, where F is force, m is mass, and a is acceleration.

Front

How do you convert kph to m/s?

Back

To convert kph to m/s, divide the speed by 3.6.

Front

What is the average speed formula?

Back

Average speed = total distance / total time.

Front

What does the term 'net force' mean?

Back

The sum of all the forces acting on an object.

Front

What is the formula for density?

Back

Density (d) = mass (m) / volume (v).

Front

What is inertia?

Back

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

Front

What is the unit of force in the SI system?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and weight?

Back

Weight (W) = mass (m) * gravitational acceleration (g).

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².
