Honors Physics Additional Review 2024 | Forces/Newton's Laws

Front

What is the formula for calculating weight (Fg) of an object?

Back

Fg = m * g, where m is mass and g is the acceleration due to gravity (approximately 9.81 m/s²).

Front

What is tension in a string or wire?

Back

Tension is the force exerted along the length of a string or wire when it is pulled tight by forces acting from opposite ends.

Front

What does it mean for an object to move at constant velocity?

Back

An object moving at constant velocity has no net force acting on it, meaning all forces are balanced.

Front

What is Newton's First Law of Motion?

Back

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

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a surface, acting perpendicular to the surface.

Front

How do you calculate the normal force on an inclined plane?

Back

Normal force (N) = mg * cos(θ), where m is mass, g is acceleration due to gravity, and θ is the angle of the incline.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, F = m * a, where F is force, m is mass, and a is acceleration.

Front

What happens when two equal and opposite forces act on an object?

Back

The object remains in its state of motion; if at rest, it stays at rest; if in motion, it continues moving at the same speed and direction.

Front

What is a free body diagram?

Back

A free body diagram is a graphical representation used to visualize the forces acting on an object.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.
