Force and Motion Flashcard

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a book on a table has gravitational potential energy.

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 the formula for calculating average speed?

Back

Average speed is calculated using the formula: Average Speed = Total Distance / Total Time.

Front

What factors affect the force in a tug-of-war?

Back

The force in a tug-of-war is affected by the strength of the teams, the friction between the ground and the players' feet, and the angle at which the rope is pulled.

Front

What is Newton's First Law of Motion?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law of Motion, the relationship is expressed as F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

How does air pressure affect the launch of a rocket?

Back

Air pressure can create thrust when it is expelled from the rocket, allowing it to overcome gravitational force and achieve motion.
