Fall 2020 EOCE Review

Front

What is the reason objects remain in the Asteroid and Kuiper Belt?

Back

Objects remain in the Asteroid and Kuiper Belt because the forces are balanced.

Front

What can an unbalanced force do?

Back

An unbalanced force can start a motion, stop a motion, or change the direction of the motion.

Front

At which point is kinetic energy highest in a swinging pendulum?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

If the mass of an object is 1000kg on Earth, what is its mass on the moon?

Back

The mass of the object remains 1000kg on the moon.

Front

What does it mean when objects have a net force of zero?

Back

Objects with a net force of zero are said to be in equilibrium.

Front

What is equilibrium in physics?

Back

Equilibrium is a state where the net force acting on an object is zero, resulting in no change in motion.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = m * g).

Front

What happens to an object in motion when a balanced force acts on it?

Back

An object in motion will continue to move at a constant velocity when a balanced force acts on it.
