Mid-Contact Forces & Newton's Laws of Motion

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law of Motion states that the acceleration of an object depends on the mass of the object and the magnitude of the force acting upon it, expressed as F=ma.

Front

What does Newton's Third Law of Motion state?

Back

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

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 the elastic limit?

Back

The elastic limit is the maximum extent to which a material can be deformed and still return to its original shape.

Front

Who formulated the laws of motion?

Back

Sir Isaac Newton formulated the laws of motion.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law of Motion 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 a net external force.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What happens to an object's motion when unbalanced forces act on it?

Back

When unbalanced forces act on an object, it will accelerate in the direction of the net force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
