Conceptual Physics Sem 1 Final Exam

Front

What is the speed of technological innovation today compared to ancient times?

Back

Innovation is much faster today than in ancient times.

Front

What does it indicate if Peyton is pulling a sled across a frictionless surface at a steady pace?

Back

The net force acting on the sled is zero.

Front

According to Newton's first law of motion, what happens to a parked car?

Back

The car will remain parked unless acted upon by a nonzero net force.

Front

What is the net force acting on a ball at the peak of its flight when thrown straight up?

Back

Equal to the gravitational force pulling it downward.

Front

What can be said about the forces acting on a bicycle cycling at a steady pace on a flat road?

Back

The forces are balanced.

Front

Define Newton's First Law of Motion.

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a nonzero net force.

Front

What is inertia?

Back

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

Front

What is the relationship between net force and acceleration?

Back

Net force is equal to mass times acceleration (F=ma).

Front

What happens to the net force when an object is in equilibrium?

Back

The net force is zero.

Front

What is gravitational force?

Back

The force of attraction between two masses, such as the Earth and an object.
