Force & Net Force

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, change direction, or change speed.

Front

What is net force?

Back

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

Front

What does it mean if forces are balanced?

Back

Balanced forces mean that the total net force is zero, and there is no change in the object's motion.

Front

What does it mean if forces are unbalanced?

Back

Unbalanced forces mean that the total net force is not zero, causing the object to accelerate or change its motion.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

If two forces of 5N and 3N act in the same direction, what is the net force?

Back

The net force is 8N.

Front

If a 10N force acts to the right and a 5N force acts to the left, what is the net force?

Back

The net force is 5N to the right.

Front

What happens to an object if the net force is zero?

Back

If the net force is zero, the object will remain at rest or continue moving at a constant speed.

Front

What is an example of unbalanced forces in everyday life?

Back

A car accelerating when the driver presses the gas pedal is an example of unbalanced forces.

Front

What is inertia?

Back

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