Net Forces & Newton's Laws

Front

What is a balanced force?

Back

A balanced force occurs when the net force acting on an object is zero, resulting in no change in motion.

Front

What happens to an object when unbalanced forces act on it?

Back

The object will move in the direction of the larger force.

Front

How does friction affect the movement of a soccer ball on a turf field?

Back

The ball moves faster on turf because the turf has less friction, allowing the ball to roll more easily.

Front

If you apply the same force to a ping pong ball and a basketball, which will accelerate more?

Back

The ping pong ball will accelerate more because it has less mass.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate.

Front

Define net force.

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

What is inertia?

Back

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

Front

State Newton's First Law of Motion.

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

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

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 the effect of mass on the motion of an object?

Back

Objects with greater mass require more force to achieve the same acceleration as lighter objects.
