MULTIPLE CHOICE QUESTION
30 sec • 1 pt
Kinetic energy is:
a push force.
the energy carried in light waves.
the energy of objects in motion.
the energy stored in food.
Answer explanation
Kinetic energy refers to the energy of objects in motion. It is the energy that an object possesses due to its movement, distinguishing it from other forms of energy like potential energy or energy stored in food.

MULTIPLE CHOICE QUESTION
30 sec • 1 pt
What two properties of an object affect its kinetic energy?
mass and weight
mass and speed
speed and distance
weight and height
Answer explanation
Kinetic energy depends on mass and speed. The formula KE = 1/2 mv² shows that both mass (m) and the square of speed (v) directly influence kinetic energy, making 'mass and speed' the correct choice.

What has a larger impact on the kinetic energy of an object and the damage in a collision?
speed
mass
weight
distance
Answer explanation
Speed has a larger impact on kinetic energy, as it is squared in the kinetic energy formula (KE = 1/2 mv²). Higher speed increases the energy and potential damage in a collision more significantly than mass or weight.

MULTIPLE CHOICE QUESTION
30 sec • 1 pt
When the mass of an object is doubled, the kinetic energy of the object:
stays the same
doubles
triples
quadruples
Answer explanation
Kinetic energy (KE) is given by the formula KE = 1/2 mv². If the mass (m) is doubled, KE becomes KE = 1/2 (2m)v² = 2(1/2 mv²), which shows that the kinetic energy doubles.

MULTIPLE CHOICE QUESTION
30 sec • 1 pt
When the speed of an object is doubled, the kinetic energy of the object:
stays the same
doubles
triples
quadruples
Answer explanation
Kinetic energy (KE) is given by the formula KE = 1/2 mv². When the speed (v) is doubled, the new KE becomes 1/2 m(2v)² = 2mv², which is four times the original KE. Thus, the kinetic energy quadrouples.
