Unit 4 Forces ~newton's laws of motion

Front

What is Net Force?

Back

Net Force is the overall force acting on an object when all the individual forces acting on it are combined. It determines the object's motion.

Front

What does Newton's First Law of Motion state?

Back

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 does Newton's Second Law of Motion state?

Back

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 of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

What is the definition of Normal Force?

Back

Normal Force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is Frictional Force?

Back

Frictional Force is the force that opposes the motion of an object when it is in contact with another surface.

Front

How does mass affect force according to Newton's Second Law?

Back

Greater mass results in a greater force required to achieve the same acceleration.

Front

What is the relationship between force and acceleration?

Back

Force is directly proportional to acceleration; as force increases, acceleration increases, provided mass remains constant.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g). (W = mg)

Front

What happens when two objects collide according to Newton's Third Law?

Back

Both objects experience equal and opposite forces during the collision.
