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 determines how much a solid object deforms?

Back

The amount of deformation in a solid object is determined by the amount of force applied and the material of the object.

Front

True or False: During a collision, objects change motion and shape.

Back

True.

Front

What does speed refer to in terms of motion?

Back

Speed refers to how fast or slow something is moving.

Front

What is inertia?

Back

Inertia is the tendency of an object to keep moving in a straight line unless acted upon by an 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 is the relationship between mass and acceleration according to Newton's Second Law?

Back

According to Newton's Second Law, as the mass of an object increases, the acceleration decreases if the same force is applied.

Front

What is the effect of a net force acting on an object?

Back

A net force acting on an object causes it to accelerate in the direction of the net force.

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.

Front

What is the principle of action and reaction?

Back

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