Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

What is the energy transformation when a battery powers a toy?

Back

Chemical to Electrical.

Front

What is the formula for calculating net force?

Back

Net Force = Force1 + Force2 (if in the same direction) or Net Force = Force1 - Force2 (if in opposite directions).

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface.

Front

What is inertia?

Back

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

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

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.
