Acceleration Unit 4 Formative

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

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 is Newton's Third Law of Motion?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object and acts in the opposite direction of the object's movement.

Front

How does friction affect the motion of an object?

Back

Friction causes a moving object to slow down and eventually stop.

Front

What is inertia?

Back

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

Front

How does mass affect the stopping distance of a vehicle?

Back

A vehicle with a larger mass requires more force to stop than a vehicle with a smaller mass.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F=ma).

Front

What role do seat belts play in a car accident?

Back

Seat belts help to restrain occupants and reduce the risk of injury by counteracting the effects of inertia during a sudden stop.

Front

What happens when two objects exert forces on each other?

Back

According to Newton's Third Law, the forces exerted by the two objects are equal in magnitude and opposite in direction.
