U4Q1 Forces and Motion

Front

What is the normal force?

Back

The 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 net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Front

What causes an object to move?

Back

A force is required to cause an object to move. This can be applied force, gravitational force, or any other type of force.

Front

What is tension in physics?

Back

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

Front

If two forces act in the same direction, how do you calculate the net force?

Back

Add the magnitudes of the two forces together.

Front

If Force 1 is 100 N to the right and Force 2 is 150 N to the right, what is the net force?

Back

Fnet = 250 N right.

Front

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, including changes in speed or direction.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

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.
