Unit 3 Newton's Second Law of Motion

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be expressed with the formula F=ma.

Front

What is the relationship between force and acceleration?

Back

Force and acceleration have a direct relationship; as force increases, acceleration increases.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

If two objects have the same mass, how does the applied force affect their acceleration?

Back

If two objects have the same mass, the object with the greater applied force will have greater acceleration.

Front

How does mass affect acceleration when the same force is applied?

Back

When the same force is applied, an object with less mass will have greater acceleration compared to an object with more mass.

Front

What is the formula to calculate acceleration?

Back

The formula to calculate acceleration is a = F/m, where 'a' is acceleration, 'F' is force, and 'm' is mass.

Front

If a force of 26 N is applied to two objects with masses of 0.52 kg and 0.78 kg, which will accelerate more?

Back

The object with a mass of 0.52 kg will have the greater acceleration.

Front

What happens to acceleration if the mass of an object is doubled while the force remains constant?

Back

If the mass of an object is doubled while the force remains constant, the acceleration will be halved.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

What is the effect of increasing force on an object with constant mass?

Back

Increasing the force on an object with constant mass will result in an increase in acceleration.
