Force, Mass, and Acceleration Practice

Front

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

Back

According to Newton's second law, force (F) is equal to mass (m) multiplied by acceleration (a), expressed as F = m * a.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

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

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as the product of mass and the acceleration due to gravity (W = m * g).

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with a surface, acting perpendicular to the surface.

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula a = F/m, where F is the net force applied to the object and m is its mass.

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

If the mass increases while the force remains constant, the acceleration of the object decreases.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

What is the effect of gravity on an object in free fall?

Back

An object in free fall experiences a constant acceleration due to gravity, approximately 9.81 m/s² downward.

Front

What is inertia?

Back

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