Equation of Motion

What do equations of motion describe?

• The temperature of an object

• The position, velocity, and acceleration of an object

• The mass of an object

• The force acting on an object

Which of the following is Newton's second law of motion?

• F = ma

• v = Δx / Δt

• a = Δv / Δt

• E = mc²

What is the relationship between force, mass, and acceleration according to Newton's second law?

• Force is directly proportional to mass and inversely proportional to acceleration.

• Force is inversely proportional to mass and directly proportional to acceleration.

• Force is directly proportional to both mass and acceleration.

• Force is inversely proportional to both mass and acceleration.

What is velocity?

• The rate of change of position with respect to time

• The total distance traveled

• The direction of motion

• The force acting on an object

What is the formula for calculating velocity?

• v = Δx / Δt

• v = F / m

• v = a * t

• v = Δt / Δx

If a car is accelerating, what is happening to its velocity?

• It is remaining constant.

• It is increasing.

• It is decreasing.

• It is changing direction.

If a ball is thrown upward, what is the direction of its acceleration at its highest point?

• Upward

• Downward

• Zero

• Horizontal

A car is moving at a constant velocity. What is its acceleration?

• Positive

• Negative

• Zero

• Cannot be determined

If you push a heavy box with a greater force, how will its acceleration change?

• It will remain the same.

• It will decrease.

• It will increase.

• It will change direction.

If you double the mass of an object, how will its acceleration change if the force acting on it remains constant?

• It will double.

• It will remain the same.

• It will be halved.

• It will become zero.
