Motion, Force, Energy and Work for Physical Science

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion, such as starting, stopping, or changing direction.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is friction?

Back

Friction is a force that resists the motion of two surfaces that are in contact with each other.

Front

What is kinetic energy?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the formula for calculating work?

Back

Work is calculated using the formula: 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.

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 Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an unbalanced force.
