Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

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 an object to accelerate, decelerate, or change direction.

Front

How does mass affect inertia?

Back

Inertia is the resistance of an object to change its state of motion. The greater the mass of an object, the greater its inertia.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by an increase or decrease in speed or a change in direction.

Front

What is constant speed?

Back

Constant speed means an object is moving at the same distance over equal intervals of time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is inertia?

Back

Inertia is the property of an object to remain at rest or in uniform motion unless acted upon by an external force.

Front

What does it mean for an object to experience acceleration?

Back

An object experiences acceleration when its velocity changes over time, which can occur due to a change in speed or direction.

Front

What is the relationship between force and motion?

Back

Force is any interaction that, when unopposed, will change the motion of an object. A net force acting on an object will cause it to accelerate.
