Forces and Motion Concepts

Front

What is static friction?

Back

Static friction is the force that resists the initiation of sliding motion between two surfaces that are in contact and at rest.

Front

What is the force responsible for the weight of an object?

Back

Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass.

Front

What is normal force?

Back

Normal force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion that arises between electrically charged particles due to their motion.

Front

What is a force?

Back

A force is a push or pull exerted on an object, which can cause it to accelerate, decelerate, or change direction.

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is the difference between mass and weight?

Back

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

Front

What is inertia?

Back

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

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is the role of tension force?

Back

Tension force is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.
