Grade 6 Science Forces

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

How can friction be reduced?

Back

Friction can be reduced by using a smooth surface, applying lubricants, or reducing the weight of the object.

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 is gravitational force?

Back

Gravitational force is the force that pulls objects toward the center of the Earth or any other celestial body.

Front

What is the unit of force?

Back

The unit of force is the newton (N).

Front

What does a spring scale measure?

Back

A spring scale measures the weight of an object, which is the force of gravity acting on it.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms (kg).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is an example of an applied force?

Back

An example of an applied force is when you push a shopping cart.

Front

What is a normal force?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object.
