Motion & Graphs
What does the slope of a velocity–time graph represent?
What is Acceleration?
What law states objects at rest stay at rest unless acted on by a force?
What is Newton's First Law?
In a vacuum, which falls faster: a rock or a feather?
They fall at the same time
What is the formula for work?
What is Work = Force × Distance?
What is the difference between speed and velocity?
What is Velocity includes direction?
If velocity stays the same on a graph, what is the acceleration?
What is zero?
What term describes an object’s tendency to resist change in motion?
What is Inertia?
Weight equals what two quantities multiplied together?
Mass × acceleration due to gravity
Wheel radius = 49 cm, axle radius = 7 cm. What is MA?
what is 7?
A car travels 40 m/s east. Another car travels 40 m/s west.
Do they have the same speed?
Do they have the same velocity?
What is they have the same speed but different velocity?
A car’s velocity changes from 60 m/s to 45 m/s in 5 seconds. What is the acceleration?
what is 3 m/s² (magnitude = 3 m/s²)?
If you double the force on an object, what happens to acceleration?
What is It Doubles?
If gravity decreases (like on the Moon), what happens to weight?
What is It decreases?
f a pulley system has 4 supporting strands, what is MA?
What is 4?
A student walks 100 meters in 20 seconds.
What is their speed?
If the student walked 50 meters east and 50 meters west in 20 seconds, what is their velocity?
What is 5 m/s and 0?
A car travels 384 meters in 4 seconds at constant speed. What is the speed?
What is 96 m/s?
When a boy pushes water backward with oars, what pushes the boat forward?
What is the water pushes back on the oars (Newton’s 3rd Law)
If mass increases, what happens to gravitational force?
What is It increases?
If mass increases, does the force needed to move it increase or decrease?
What is Increase?
Car A: 100 meters in 10 seconds
Car B: 150 meters in 10 seconds
Which is faster?
On a velocity-time graph, during which interval is velocity constant?
What is When the line is horizontal?
Two carts are released from a compressed spring. One has twice the mass. Which has greater acceleration?
What is the smaller mass cart?
On Earth, all objects dropped in a vacuum accelerate at what rate?
What is 9.8 m/s²?
1.) If an object weighs 50 N and is lifted 35 m, how much work is done?
2)If no distance is moved, how much work is done?
What is 1750 J and Zero?
A car travels 60 meters in 6 seconds at a constant speed.
Then it stops and remains still for 4 seconds.
What is the car’s average speed for the entire 10 seconds?
What is 6 m/s?
