What is inertia?

Back

Inertia is the tendency of an object to resist changes in its motion. It is directly related to the mass of the object; the greater the mass, the greater the inertia.

What does Newton's 1st Law state?

Back

Newton's 1st Law states that an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside force.

Front

What is the relationship between action and reaction forces according to Newton's 3rd Law?

Back

According to Newton's 3rd Law, for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces acting on it are combined. It determines the object's acceleration.

Front

How many variables should be changed in a scientific experiment?

Back

In a scientific experiment, only one variable should be changed at a time to ensure that the results are valid.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the formula for calculating force?

Back

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

Front

What is the difference between mass and weight?

Back

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

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 the significance of a balanced force?

Back

A balanced force occurs when the net force acting on an object is zero, resulting in no change in motion.
