Newton's 2nd Law of Motion

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be expressed with the formula: F = ma (Force = mass x acceleration).

Front

What does the term 'force' mean in physics?

Back

Force is a push or pull acting upon an object resulting from its interaction with another object. It is measured in Newtons (N).

Front

What unit do we measure force in?

Back

Force is measured in Newtons (N).

Front

How does mass affect the force needed to change an object's motion?

Back

The larger the mass of an object, the more force is required to change its motion.

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time. It can be caused by a change in speed or direction.

Front

If two objects are pushed with the same force, how does their mass affect their acceleration?

Back

The object with less mass will accelerate more than the object with greater mass when pushed with the same force.

Front

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

Back

The relationship is described by Newton's 2nd Law: F = ma, meaning force equals mass times acceleration.

Front

Can an object have a constant speed but still be accelerating?

Back

Yes, an object can be accelerating if it is changing direction while maintaining a constant speed.

Front

What happens to the acceleration of an object if the force acting on it is doubled?

Back

If the force is doubled, the acceleration of the object will also double, assuming the mass remains constant.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.
