What is the effect of air resistance on falling objects?

Back

In the absence of air resistance, all objects fall at the same rate regardless of their mass.

Front

Define friction in the context of motion.

Back

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

Front

What type of force is tension?

Back

Tension is a pulling force transmitted through a string, rope, or cable when it is pulled tight.

Front

How does gravitational force change with altitude?

Back

Gravitational force decreases as you move to higher altitudes.

Front

What are the two forces acting on a cart moving down a ramp?

Back

Friction and Gravity.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the mass of the objects involved.

Front

Explain the concept of net force.

Back

Net force is the vector sum of all the forces acting on an object.

Front

What happens to an object at rest when no net force acts on it?

Back

It remains at rest due to Newton's First Law of Motion.

Front

What is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

Define shear force.

Back

Shear force is a force that causes parts of a material to slide past each other.
