Force and it's effects

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in a net force of zero.

Front

What is the S.I. unit of force?

Back

The S.I. unit of force is the newton (N).

Front

What effect does force have on an object's shape?

Back

Force can change the shape of an object, such as stretching or compressing it.

Front

When do we use force as a push?

Back

We use force as a push when we move objects away from us, like moving books.

Front

When is force applied as a pull?

Back

Force is applied as a pull when we are trying to bring objects closer, like in a tug of war.

Front

What is net force?

Back

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

Front

What happens when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant speed.

Front

What is an example of a force changing the direction of motion?

Back

An example is when a soccer player kicks a ball, changing its direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting between surfaces in contact.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling us down.
