Amplify Force and Motion End of Unit Flashcard

Front

What is force in the context of motion?

Back

Force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

How is the strength of a force measured?

Back

The strength of a force is measured in Newtons (N).

Front

What factors affect the force experienced by an object during a collision?

Back

The mass of the objects involved and the change in velocity during the collision affect the force experienced.

Front

What is the relationship between mass and force in motion?

Back

According to Newton's second law, force equals mass times acceleration (F=ma), meaning greater mass requires more force to achieve the same acceleration.

Front

How can you determine which object experienced the strongest force in a collision?

Back

The object that experiences the greatest change in speed or direction typically experienced the strongest force.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can be caused by a change in speed or direction.

Front

What is the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

Front

How does mass affect acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases when the same force is applied, according to F=ma.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, kinetic energy is conserved, while in inelastic collisions, kinetic energy is not conserved.

Front

What role does friction play in motion?

Back

Friction is a force that opposes motion between two surfaces in contact, affecting acceleration and speed.
