What is net force?

Back

Net force is the total force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

How do you calculate net force when forces are acting in opposite directions?

Back

To calculate net force, subtract the smaller force from the larger force. The direction of the larger force will be the direction of the net force.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion. Unbalanced forces cause a change in motion.

Front

What is the definition of climate?

Back

Climate refers to the long-term average of weather conditions in a particular area over a significant period.

Front

What is the definition of weather?

Back

Weather refers to the short-term atmospheric conditions in a specific place at a specific time.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

Front

If a team pulls with 25N and another with 35N, which team has a greater force?

Back

The team pulling with 35N has a greater force.

Front

What happens to an object in motion if the net force acting on it is zero?

Back

If the net force is zero, the object will continue to move at a constant speed in a straight line or remain at rest.
