Front

What is Newton's Third Law of Motion?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

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

Back

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

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in motion.

Front

Where does a ball have maximum kinetic energy when rolling down an incline?

Back

At the bottom of the incline.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between mass and weight?

Back

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

Front

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

Back

The kinetic energy increases by a factor of four, since KE is proportional to the square of the speed.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as an object and the Earth.
