6th Grade Semester Exam Review

Front

What is friction?

Back

Friction is a force that opposes motion when two surfaces rub against each other.

Front

What happens when the net force on an object is 0 Newtons?

Back

The object will not change its motion.

Front

What type of force is exerted by magnets?

Back

Magnetism is the force exerted by magnets.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause a change in an object's motion.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object has due to its position in a gravitational field, such as a rollercoaster at the top of a hill.

Front

What is the definition of gravity?

Back

Gravity is the force that attracts two bodies toward each other, commonly experienced as the force that pulls objects toward the Earth.

Front

What is an example of kinetic energy?

Back

A moving car is an example of kinetic energy, which is the energy of motion.

Front

What is the difference between mass and weight?

Back

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

Front

What is the formula for calculating force?

Back

Force is calculated using the formula: Force = Mass x Acceleration (F = m x a).

Front

What is inertia?

Back

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