Review for Forces and Newton's Laws of Motion

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

Define displacement.

Back

Displacement is the distance and direction an object has travelled from its starting point.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length travelled, while displacement is the shortest straight line from the starting point to the endpoint, including direction.

Front

What does Newton's First Law state?

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 an unbalanced force.

Front

What does Newton's Second Law state?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What does Newton's Third Law state?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

What is the formula for calculating speed?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula: Momentum = Mass x Velocity.
