Forces and Motion Concepts Ch1

Front

What is Newton's 3rd Law?

Back

When one object exerts a force on a second object, the second object exerts an equal force in the opposite direction.

Front

What is a contact force?

Back

A force that requires physical contact between two objects, such as a baseball being hit by a baseball bat.

Front

What is a non-contact force?

Back

A force that acts at a distance without physical contact, such as gravitational force or magnetic force.

Front

How do you calculate net force?

Back

Net force is the total force acting on an object, calculated by adding all the forces acting in one direction and subtracting those acting in the opposite direction.

Front

What is a force pair?

Back

The force that two objects exert on each other, as described in Newton's 3rd Law.

Front

What is friction?

Back

A force that opposes the motion of an object, acting in the opposite direction of the object's movement.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is acceleration?

Back

The rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What is the relationship between mass and force?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).
