Force, Energy and Motion

Front

What is work in physics?

Back

Work is done when a force causes an object to move. It is calculated as the product of the force applied and the distance moved in the direction of the force.

Front

What is the formula for calculating work?

Back

Work = Force x Distance

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a girl on a diving board has potential energy because she is elevated above the water.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

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 can cause an object to accelerate or change direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as chemical energy to thermal energy in a rocket.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object.
