Worksheet time: 10mins
When an object is acted on by unbalanced forces, the object will always —
accelerate
continue in the same direction
continue at the same speed
come to a stop
A student pushes a box with a force of 16 N to the left. Another student pushes the same box from the opposite side with a force of 8 N to the right.
According to the above information and diagram, what will be the result?
The box will move to the right with an 8 N force.
The box will move to the right with a 2 N force.
The box move to the left with a 2 N force.
The box move to the left with an 8 N force.
The graph below represents the movement of an object.
Which description best fits the motion shown on the above graph?
An airplane taking off and reaching a constant cruising speed
A roller coaster traveling up and down the first hill
A car traveling at a constant speed and stopping to refuel
A roller coaster traveling down a hill and climbing the next hill
A 2000 kg truck and a 500 kg car are racing. The same amount of force is applied to each of them.
Which statement below best describes the acceleration of the vehicles?
The truck will accelerate twice as fast.
The car will accelerate four times as fast.
The car will accelerate twice as fast.
The truck will accelerate four times as fast.
One of the laws of motion states, "An object in motion stays in motion unless an unbalanced force acts upon it." On Earth, objects always seem to eventually come to a stop when more force is not being applied.
What force is causing the objects to eventually stop moving?
mass
friction
weight
gravity
Two vehicles were involved in an accident. Vehicle A has a mass of 1,447 kg, and Vehicle B has a mass of 1,310 kg. Both vehicles were traveling at 20 km/hr at the time of collision.
What will most likely be the outcome of this collision?
Vehicle A will have no change in speed and be pushed to the left because it has a smaller mass.
Vehicle A will have a change in speed and be pushed to the left because it has a larger mass.
Vehicle B will have no change in speed and be pushed to the left because Vehicle A has a larger mass.
Vehicle B will have a change in speed and be pushed to the right because Vehicle A has a larger mass.
A conveyor belt is helpful when loading boxes onto a truck.
Which statement accurately represents the net force of the boxes moving along a conveyor belt at a constant speed of 0.5 m/s?
Forces on the boxes are unbalanced.
The net force on the boxes is only due to gravity.
Forces on the boxes are balanced.
The net force on the boxes cannot be determined.
If a car is moving on a road at 70 km/hr going due north and then changes direction and starts traveling north-east staying at 70 km/hr, what happens to its speed and velocity?
The speed of the car changes, but the velocity stays the same.
Both the speed and velocity of the car change.
Neither the speed nor the velocity of the car changes.
The velocity of the car changes, but the speed stays the same.
Which of the following statements best describes how the speed and velocity of an object differ?
Velocity specifies speed and direction, while speed has no specific direction.
Velocity specifies speed, while speed includes a specific direction.
Velocity specifies a change in speed over time, while speed specifies a change in distance over time.
Velocity specifies a change in distance over time, while speed specifies a change in velocity over time.
A student was traveling to see his grandmother who lives 15 miles north of his home. He started from rest and maintained a pace of 4m/s before stopping at his grandmother’s house for lunch.
Which of the following best describes the speed, velocity, and acceleration of the student’s walk?
He traveled at a speed of 4m/s north with a velocity of 4m/s north, and his acceleration increased before stopping for lunch.
He traveled at a speed of 4m/s with a velocity of 4m/s, and his acceleration increased before stopping for lunch.
He traveled at a speed of 4m/s with a velocity of 4m/s north, and his acceleration changed when stopping for lunch.
He traveled at a speed of 4m/s with a velocity of 4m/s north, and his acceleration did not change when stopping for lunch.
A student rides the Ferris wheel when visiting an amusement park. During the ride, she moves at a constant speed of 3 m/s.
Which of the following statements best describes the motion of the student on the Ferris wheel?
The velocity is changing because the direction is changing.
The velocity is not changing because the speed is constant.
The velocity is increasing because the direction is changing.
The velocity is decreasing because the speed is constant.
A force that will work against motion in every situation is —
the normal force
weight
gravity
friction
During a tug-of-war competition, neither team is able to gain an advantage. Which of the following explains the forces in this situation?
The forces are balanced.
The forces are overcome by air friction.
The mass of the rope cancels the forces being exerted on it.
The forces are unbalanced.
A rocket is traveling from Earth to Mars at 10,000 m/s. If no outside force is applied to it, what will happen to its speed over the course of the trip?
Speed up
Slow down
Stay constant
Changes depending on mass
Two vehicles with different masses are traveling 104 kilometers per hour on a highway. As each vehicle approached a traffic light, it turned red. Each car applied their brakes at the same time and applied the same amount of force to stop.
Which statement below best describes what happened?
The vehicle with the larger mass took longer to stop than the vehicle with the smaller mass.
The vehicle with the smaller mass took longer to stop than the vehicle with the larger mass.
The vehicle with the smaller mass has more inertia than the vehicle with the larger mass.
The vehicle with the larger mass took less force to stop than the vehicle with the smaller mass.
