Pre AP ICP - Unit 10 Review

Front

What is the formula to calculate mass from force and acceleration?

Back

Mass (m) = Force (F) / Acceleration (a)

Front

If a force of 250 N causes an object to accelerate at 5 m/s², what is the mass of the object?

Back

50 kg

Front

What is inertia?

Back

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

Front

According to Newton's 2nd Law, what is the relationship between force, mass, and acceleration?

Back

Force = Mass × Acceleration (F = m × a)

Front

What is the weight of an object with a mass of 100 kg?

Back

Weight (W) = Mass (m) × Gravity (g); W = 100 kg × 9.8 m/s² = 980 N

Front

What is the definition of frictional force?

Back

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

Front

What is Newton's 1st Law of Motion?

Back

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

Front

What is the definition of thrust?

Back

Thrust is the force that moves an object forward, often used in the context of engines or rockets.

Front

What is buoyant force?

Back

Buoyant force is the upward force exerted by a fluid on an object immersed in it.

Front

If an object has a weight of 980 N, what is its mass?

Back

100 kg (using W = mg, where g = 9.8 m/s²)
