What is the difference between mass and weight?

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

• Mass is the force exerted by gravity, while weight is the amount of matter in an object.

• Mass and weight are the same and can be used interchangeably.

• Weight is the measure of an object's volume, while mass is the measure of its density.

What happens to an object's kinetic energy if its speed doubles?

• The kinetic energy remains the same.

• The kinetic energy increases by a factor of two.

• The kinetic energy increases by a factor of four.

• The kinetic energy decreases by a factor of four.

What is the relationship between mass and weight?

• Weight is the force of gravity acting on an object's mass.

• Mass is the force that acts on an object due to its velocity.

• Weight is the measure of how much matter is in an object.

• Mass and weight are the same and can be used interchangeably.

What is Newton's Third Law of Motion?

• For every action, there is an equal and opposite reaction.

• An object in motion stays in motion unless acted upon by an external force.

• The force of gravity is proportional to the mass of the objects involved.

• The acceleration of an object is directly proportional to the net force acting on it.

What is kinetic energy?

• The energy an object possesses due to its motion.

• The energy stored in an object due to its position.

• The energy released during a chemical reaction.

• The energy associated with the temperature of an object.

How does elevation affect the weight of an object on Earth?

• The weight of an object increases with higher elevation.

• The weight of an object remains the same regardless of elevation.

• The force of gravity acting on the object decreases with higher elevation.

• The weight of an object is unaffected by elevation changes.

How do frictional forces affect motion?

• Frictional forces have no effect on motion.

• Frictional forces cause objects to speed up.

• Frictional forces oppose motion, causing objects to slow down or stop.

• Frictional forces only affect objects at rest.

What is the principle of conservation of energy?

• Energy can be created and destroyed.

• Energy can only be created.

• Energy cannot be created or destroyed, only transformed from one form to another.

• Energy is always lost in transformations.

What are balanced forces?

• Forces that are equal in size but opposite in direction, resulting in no change in motion.

• Forces that are unequal in size and act in the same direction, causing acceleration.

• Forces that are equal in size and act in the same direction, resulting in a net force of zero.

• Forces that change the motion of an object by acting in opposite directions.

What is inertia?

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

• Inertia is the force that causes an object to accelerate.

• Inertia is the mass of an object multiplied by its velocity.

• Inertia is the energy stored in an object due to its position.
