Front

What happens when forces acting on an object are balanced?

Back

The net force is Zero.

Front

What is the primary method of heat transfer when you feel warmth from the sun on your skin?

Front

According to Newton's First Law, what can we conclude about the forces acting on a ball rolling at a constant velocity on a frictionless surface?

Front

If a car is moving at a constant speed on a straight road, what can be said about the forces acting on it?

Back

The forces are balanced.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

Define net force.

Back

Net force is the vector sum of all the forces acting on an object.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

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 by the movement of fluids (liquids or gases).
