Front

What is a balanced force?

Back

A balanced force is a force pair that has a net force of zero, meaning the forces acting on an object are equal in size and opposite in direction.

Front

What happens to two objects thrown horizontally from the same height but at different velocities?

Back

They will have the same acceleration due to gravity and hit the ground at the same time.

Front

If the mass in an Atwood machine is increased, how does it affect acceleration?

Back

Increasing the mass generally results in less acceleration if the total mass increases.

Front

What is the formula to calculate force using Newton's second law?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the formula to calculate acceleration using Newton's second law?

Back

a = F/m, where a is acceleration, F is force, and m is mass.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that results in a net force acting on an object, causing it to accelerate.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

Mass and acceleration are inversely related; as mass increases, acceleration decreases if the force is constant.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, affecting their acceleration and terminal velocity.
