Mid-Contact Forces & Newton's Laws of Motion

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, as it is not countered by an equal and opposite force.

What is friction?

Back

Friction is a force that opposes the motion of an object, acting against sliding, rolling, or static movement.

Front

What determines how much a solid object deforms?

Back

The amount of force applied and the material of the object determine how much a solid object deforms.

Front

What is the elastic limit?

Back

The elastic limit is the maximum extent to which a material can be deformed and still return to its original shape.

Front

What is Newton's 1st Law of Motion also known as?

Back

Newton's 1st Law is also known as the Law of Inertia.

Front

What is inertia?

Back

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

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding over each other.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = m * a, where F is force, m is mass, and a is acceleration.

What is the role of gravity in motion?

Back

Gravity is a force that attracts objects toward each other, influencing their motion and acceleration.

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass * gravity.
