Newton's Laws of Motion CCA #3 Hyperdoc

Front

What type of force(s) will cause a change in an object's motion?

Back

Unbalanced forces cause a change in an object's motion.

Front

What is the unit of mass?

Back

The unit of mass is kilograms (kg).

Front

What does 45 m/s² represent?

Back

45 m/s² is an example of acceleration.

Front

If a bike accelerates at 10 m/s² when a force of 50N is applied, what is the mass of the bike and its rider?

Back

The mass of the bike and its rider is 5 kg.

Front

What unit do we measure force in?

Back

Force is measured in newtons (N).

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 an unbalanced 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 to calculate force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight (W) = mass (m) × gravitational acceleration (g).
