Forces & Newton's Laws REVIEW

Front

What is the formula to calculate force?

Back

Force = Mass × Acceleration

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.

Front

What is buoyancy?

Back

Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in it.

Front

What are the two main forces acting on a baseball thrown into the air?

Back

Air resistance and gravity.

Front

If an object has a mass of 300 kg and an acceleration of 600 m/s², what is the force acting on it?

Back

180,000 N

Front

What does it mean for forces to be balanced?

Back

Balanced forces mean that the net force acting on an object is zero, resulting in no change in motion.

Front

What is the net force if two equal forces of 5 N are acting in opposite directions?

Back

The net force is 0 N.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

Front

What is air resistance?

Back

Air resistance is a type of frictional force that opposes the motion of an object through the air.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, acceleration decreases if the force remains constant.
