Students are going to conduct an experiment to study the effect of a net force applied to an object on the object’s motion. In each trial of the experiment, the students will apply a net force on the object. They also need to take two other measurements. What are the other quantities they should measure in each trial of the experiment?
acceleration and time acceleration and time mass and acceleration mass and acceleration mass and velocity mass and velocity velocity and time
The other quantities that the students should measure in each trial of the experiment are mass and acceleration.
Which statement makes an accurate comparison of the motions for objects C and D?
Without knowing the specific characteristics of objects C and D, it is not possible to accurately compare their motions.
Use the equation for motion to answer the question. x=x0+v0t+12at2 An object has a starting position of 2 m, a starting velocity of 15 m/s, and is moving at a constant speed. Which option shows the final position of the object after 1 s?
32 m 32 m 60 m 60 m 17 m 17 m 30 m
To find the final position of the object after 1 s, we can use the given values in the equation for motion:
x = x0 + v0t + (1/2)at^2
Given:
x0 = 2 m (starting position)
v0 = 15 m/s (starting velocity)
t = 1 s (time)
Plugging in the values:
x = 2 + 15 * 1 + (1/2) * 0 * (1^2)
x = 2 + 15 + 0
x = 17 m
Therefore, the final position of the object after 1 s is 17 m.
The graph of an object's position over time is a horizontal line and y is not equal to 0. What must be true about the object's motion?
The acceleration is constant and non-zero. The acceleration is constant and non-zero. The velocity is constant and non-zero. The velocity is constant and non-zero. The acceleration is negative. The acceleration is negative. The velocity is zero.
In each trial of the experiment, the students should measure the two other quantities: mass and acceleration.
To measure the mass of an object, the students can use a balance or a scale. They should weigh the object before conducting the experiment. Mass is a measure of the amount of matter in an object and it remains constant regardless of the location of the object.
To measure acceleration, the students can use a motion sensor or a stopwatch. Acceleration is the rate at which an object's velocity changes over time. They can measure the time it takes for the object to accelerate from rest to a certain velocity or the time it takes for the object to decelerate. Alternatively, they can use a motion sensor to directly measure the acceleration of the object.
By measuring mass and acceleration, the students can calculate the net force acting on the object using Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = m*a). This will help them understand the effect of a net force on the object's motion.
