Newton's Laws Review

What is Inertia?

Back

Inertia is the resistance of an object to change its state of motion. It means that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = M x A).

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object. If forces are in opposite directions, subtract the smaller force from the larger force.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = M x A, where F is force, M is mass, and A is acceleration.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be calculated using the formula A = F / M.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact with each other.

Front

What is an unbalanced force?

Back

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

Front

What is the relationship between mass and acceleration?

Back

According to Newton's Second Law, for a given force, an increase in mass will result in a decrease in acceleration.

Front

What is the effect of inertia on a moving object?

Back

Inertia causes a moving object to continue moving in a straight line at a constant speed unless acted upon by an external force.
